no oil pressure??

ok I have searched and I think I have found some answers, but I want to make sure I am reading everything correctly that i should check. ok yesterday i was driving and i noticed my oil pressure was very low, the needle was maybe a little less than 1/4 of the way up the gauge. today i started my car and the gauge shows absolutly NO oil pressure! the needle is all the way at the bottom. so if i read previous threads correctly, i have to check the oil sending unit which is a little round peice on the drivers side that screws into.... i cant remember and has a black wire comming out the top of it correct??, then check the oil pump, where is the oil pump located??? and how hard is it to install a new one???

Thanks,
Steve

it would probablly be a bad oil pump.

changing the oil pump is something you should have a mechanic do. the degree of dificulty depends on where the oil pump is located, and what type of oil pump it is

I'm not sure what you can check on the oil pressure sending unit other then make sure the wire is attached. The oil pump is a pretty big job. It's on the timing cover and if I remember, it requires removing a significant portion of the timing side of the engine including the timing belt. If you are not familiar with cars, it's probably a good idea to either get help doing it or have it done at a shop.

wonder how much that would cost. but the oil sending units can go bad cant they? so should i try that first?

Oil sending units can very well go bad. They are relitivly inexpensive around $12. I would take a drive down to your local Mitsubishi dealership on monday and pick one up.

The stock oil pressure gauge is useless. I would recomend spending $65 and buy an autometer electirc oil pressure gauge. Mechanical ones are simpler, quicker to install & slightly more accurate. But there is somthing about having oil coming into the cab of my car that frightens me. If you choose to go that route i will cirtanly talk you through it.

If that fails, you will want to have a dealership, or trusted mechanic install the oil pump assembly. But labor will be ENORMUS! its more work then doing a timing belt.

damn i hope its the oil sending unit! lol by the way, last time i got my oil changed i took it to Valvoline like a dumbass about 2,000 miles ago, instead of doing it myself b/c i was to lazy to, and i am wondering if they put the correct oil filter on, b/c dont you have to have an oil filter that can handle the oil pressure that our engines need? and i was wondering if that could be a problem, would they have the sending unit at the local autoparts store?? like autozone ect??? so i think i am just going to change my oil and filter and replace the oil sending unit while im at it and keep my fingers crossed! sound like a plan??? wish me luck everyone! lol

by the way i do have an aftermarket oil pressure gauge, boost gauge, and air fuel gauge, but the oil sending unit (i think thats what it is???) they gave me with it doesnt fit, i think its to big, but my friend was helping me install it and he is the one that tried it so it doesnt work right now, so i might just try it again when i change my oil

good call on the filter. Never use anything but OEM filter. So you have a oil gauge thats not connected?

yeah the aftermarket gauge isnt connected b/c my friend couldnt get the oil pressure sending unit on the car that the gauge came with, but the other two gauges are connected and work fine lol but i hope to fix it tomorrow when i change my oil

Mechanical ones are simpler, quicker to install & slightly more accurate. But there is somthing about having oil coming into the cab of my car that frightens me.


Most shops here in CA will outright refuse to install mechanical ones for that very reason, as I discovered after blowing $55 on an OBX POS oil pressure guage.

I'm almost 99% sure that it's your sending unit. Let me know.

ok thanks! that makes me feel better tsipsi! i hope your right! im going to go change the oil, filter, and sending unit right now, ill let you guys know! thanks for all of your help!

well i have some bad news, i replaced the oil sending unit (hopefully correctly) and still absolutly NO oil pressure im mean the needle doesnt move! it just sits on the VERY bottom :( i have a feeling this is gonna be an expensive repare for any oil pump and labor

anyone know roughly how much a fuel pump is to get installed??? (parts, and labor)

did you replace the factory oil pressure sending unit with an OEM one? or did you eliminate it, and install Autometers one w/ gauge?

if your oil light isn't on, it could be your gauge in the dash.. you need to T off the stock and autometer sending units from the oil housing. if you eliminate the stock sending unit the Oil light will come on. If you installed the electric sending unit and gauge, and your pressure is still weak, or non-existant then its going to $$ ya.

there are no lights on; on the gauge cluster that say any thing about low oil or what ever. i replaced the stock oil sending unit with the kind that came with my "glow shift" gauges. they arent autometer. here is what i did, i took out the old oil sending unit, then i took off the wire that is connected to it on top, cut the wire to where i could splice a little peice of wire onto it to ground it or what ever onto the top of the new sending unit (sinse they were different on top), then i pluged in the stock male and female ends for the power wire and spliced the power wire to my Glow Shift gauge into the stock oil gauge wire, and screwed in the aftermarket sending unit. lol sorry i explained it the best i could :( i wish i knew how to put pics on here. does it sound like its connected correctly?

What do you mean did i eliminate it??? i dunno lol i took it off completely lol so i guess, but i dont know if thats the right way lol How and why do i have to T off both sending units? i cant just take out the stock one and screw in the aftermarket one?

do you think the two black male and female conectors that connect the wire on top of the oilsending unit to the stock power wire for the stock gauge could go bad, b/c when i was looking at them they had oil in them, i dont know if this could make a difference or not??

Here's the basis of my prediction. I have two talon's that reside in my garage, both of which read no oil pressure, both of which have shitty sending units. At least 50% of the DSM guys I ride around with do not have working oil pressure guages. This is a common thing in these cars. I'm still gonna stand by my original post, but I'd realllly like to see if you prove me wrong. Good luck, and definitely recheck all your connections.

i had no oil presure the other day, it was because i had no oil... yeah it was all in my radaitor, boiling out and pouring on the ground.... fun fun

is there a way to check to see if oil is getting to my engine?? maybe it is just the gauge? i dont know, when i take off the oil cap everything looks lubed up in there??? and i dont hear it running any different?? wouldnt it sound like metal on metal or run rough or something if it wasnt getting any oil??? b/c it runs fine, i cant feel any difference??

anyone know??

arrrg. spend the 62 dollars for an autometer setup. install it correctly. oil pressure is somthing you need to fix or you'll kill your engine. You must have a reliable Oil Gauge and sending unit!!!

my gauge is BRAND NEW, so is the oilsending unit! so i dont see how they arent reliable??? so i dont see what the problem is, and i am asking if it sounds like i hooked it up correctly thats all...... didnt know it was such a big deal to you....... sorry.... with that said does it sound like its hooked up correctly?

Are you still driving the car? So are you saying you connected the aftermarket sending unit to the stock gauge line? If so the stock gauge is probably not getting proper voltage therfore its still not reading pressure.

no Im not driving the car, i am driving my beater 92 Probe LX.
o really??? thats interesting?? i never thought of that! yes i do have them both hooked up to the same wire. so should i try running just the aftermarket gauge and just run the power wire from the gauge directly to the oil sending unit?

Its hard to say, is the power to light the gauge? Did the gauge come with any instructions as to what to do with the power?

yeah the aftermarket gauge lights up, there were instructions, but im not sure what i did with them lol

ok so i have been reading more, and i have seen that some people say there is more than one oil pressure sending unit, one for the low oil light, and one for the gauge?? or is that just for the 1gens?

ok i just went out and turned my key, to turn on the acessories and the turbo gauge moved, the engine temp moved a little, of course the fuel gauge didnt lol b/c its not suppose to, but..... the oil pressure gauge didnt move one bit, it think its suppose to isnt it??? if it is, do you think there is a wire that is messed up somewhere?

Well, like we said, that stock gauge is absolutly useless. the only real use of the stock sending unit will be to alarm you with a Low Oil Pressure light that will come on if their is abnormalities in the sending supply.

If you have 100% faith in your aftermarket sending unit & gauge then my all means install it. It is truly the only way to watch true oil pressure.

I did a write up on how to install an aftermarket Gauge and Sending unit. you might want to look into it.

but my gauge has worked fine before. Im sure its not so inaccurate (sp?) that it would show absolutly NO, oil pressure at all. so if my low oil pressure light isnt on then its probably not my oil pump correct?? and like i said before my stock gauge needle didnt move at all when i turned the key to accessory so doesnt that mean the gauge is F*cked up?

You know i like you Black97GST, but your not giving me alot here. If your stock oil pressure guage caught fire, melted, was reincraneted as a cow that took a shit on your seat; That shit would provide more accurate oil pressure information then the stock gauge. BUT THEN AGAIN WHAT THE FUCK DO I KNOW!

Keep the stock sending unit, T off the aftermarket one from the filter housing, install everyting correcly to your gauge and read your oil pressure.

After you've correctly installed the aftermarket sending unit and gauge, and the oil pressure is still very, very low it will 90% more then likly be your oil pump, or a leak in the block making it loose oil pressure. Like having an oil squirter come off and lay in the bottem of your oil pan. of just the aftermarket filter. there are not manny things it can be. But square 1 is getting accurate readings....... No oil light, no huge delema.

Here is what mine looks like from the filter housing. you can see that i remote mounted my sending unit to the firewall (well not really, but you can see the steal braided line thats connected to the Brass fitting that runs up to the firewall)!!

lol what do you mean im not giving you a lot? lol i think i have given a lot of info on my problem. ok so since there is no oil light, like you said. it most likely isnt a real big problem correct? which means its most likely not the oil pump correct? lol so you basically typed all that to tell me at the end that its not a big problem?? im not trying to be an ass by any means, i appreciate your help and all you have done for me, im just trying to get all of this you just typed straight. also where could i get the "T" to T off the oil pressure sending units? any autoparts store??

Thanks a lot

also why did you remote mount yours to the firewall?? does this give a more accurate reading?? do i have to do that?

Dude if you have no oil pressure... its your oil pump. Same thing happend to my car so we changed the oil pump.

lol!!! wow and thats the only thing that can be wrong huh?? lol b/c i have read MANY posts on here and dsmtuners and 99% of them say its most likely the oil pressure sending unit is bad or the wire is damaged, or the gauge is bad. and also i find it VERY hard to believe that its the oil pump if the light isnt on, and the gauge doesnt move one bit when you turn the key, it sits at the VERY bottom. even if it was the oil pump it would most likely show a tiny bit of oil pressure.

so sinse the oil pressure light/ idiot light isnt on then should i be real worried? b/c i think if that isnt on (and i know its not burnt out) then its probably just the gauge its self, or a bad connection. sound good to n e one?? lol

an oil pressure sending unit at AutoZone is $54.00!! thats a lot more than i was thinking it would be, so i didnt buy it yet, so any help would be appreciated.

GOOD NEWS EVERYONE!! i just installed a mechanical oil pressure gauge and my oil pressure is just fine! at idle it is about 25psi and driving on the high way it is 75-80 i am sooo happy now! thanks EVERYONE for all of your input. Damn stock gauge!

hummm. bad gauge hu? Glad you could get that tracked down!

Could you (Black97GST) please type all of your thoughts into one post at a time, cause It's a bit rediculous when I'm reading along and all I'm reading is what your saying post after post after post. Cause on this page 10 out of 15 of the posts were yours. So please gather all of your thoughts for like... idk like and a day and make one maybe two posts and believe it or not that would be enough.

That goes for you too. If your going to step on a limb and bash somone, try and make sure you use articulate sentences. :grinyes:

OWN3D!!!! and by the way ned, I have been here longer than you have and I am a member of DSMTuners, I think i know how to post, and as you see, there are also people asking me questions in there too and this last page was me trying things out and letting everyone know the out come. but thanks anyway, and most of your posts on here you are trying to tell people how to post correctly, why not actually give them useful information instead of complaining how much and what you have to read. If you dont like to read about problems then this isnt a ver good place for you. Do you not have anything else to do than bash people??? Do you think your a mod or something?? sorry i just cant stand bashers.

sorry Josh im done i just had to get that out

I'm almost 99% sure that it's your sending unit. Let me know.

ohhhh shit... I'm feeling an "I told you so" coming on ... ahhh yep... I told you so.

yeah but its not the sending unit lol its the gauge its self b/c i tried a different oil pressure sending unit, but it didnt work lol (that could be b/c i discovered that the ground wire was trapped under my strut tower bar and was smashed in half :) soooo yeah you most likely told me so lol)
THANKS EVERYONE!

lol what do you mean im not giving you a lot? lol i think i have given a lot of info on my problem. ok so since there is no oil light, like you said. it most likely isnt a real big problem correct? which means its most likely not the oil pump correct? lol so you basically typed all that to tell me at the end that its not a big problem?? im not trying to be an ass by any means, i appreciate your help and all you have done for me, im just trying to get all of this you just typed straight. also where could i get the "T" to T off the oil pressure sending units? any autoparts store??

So maybe it does seem like bashing but it looks to me that your a bit on the cocky side :gay:. And when somebody tells you what your problem most likely could be, don't be a dick about it when they're voluntarily helping you. Also in what other threads have I posted about how other people say things?

So I am still here to help and sorry for the bashing ment no disrespect to any one if I offended anybody. So what have you found out about your problem? I don't really know much about the Oil sending unit or the gauge but could you just have a bad power wire to the gauge, idk.

lol how do i seem cocky?? lol thats weird b/c i dont see one thread that i have posted where i am acting cocky, that last one i posted b/c i was pissed that you didnt have any input in this WHOLE thread, but you managed to tell me "to learn how to postand didnt help me at all" but im done with this so if you wanna talk about it more then just pm me. but im cool with you so please dont keep starting stuff.
as far as the gauge, yes there probably is a problem with the grounding wire that goes on top of the sending unit.
