just joined and need help badly

Hello i just found your forum not sure if its the right place to ask this but here i go.i have a 1994 s10 blazer with the 4.3ltr. 5 days ago i noticed a coolant leak. So i drained the system and refilled it. I am pretty sure its the water pump. Ok straight forward for me. 2 days later topped off coolant drove 2 miles came home. Sat for 8 hours then went out. Truck wouldnt start. couldnt figure why. noticed oil dipstick was bone dry, but havent been leaking oil. Next day got i jump started ran it for 40 mins then shut off. Next morning wouldnt start. Bought oil at local store added 2 qts, still no oil on stick. tried in vain to charge battery thinking it wasnt cranking enough. next day added 2 more qts of oil, still none on dipstick. Tried to jump it with no luck, the engine does look to be turning over fine thou i will add. I am very poor right now and this is our only vehicle. Any help would be sooooo appreciated thanx.

smokey joe out of the tail pipe or is it just dissaperaing? and are you still loseing coolent or was it the pump?

Welcome to Auto Forums mossin69 :cheers:
Whatever you do don't start your truck until you see oil close to the full mark on the dipstick.
You might not have enough oil in there for the truck to start.

If it still doesn't start you'll have to look for spark and if you have spark then you'll have to look for fuel

Right now it's a good thing that your vehicle isn't starting as if the dipstick is correct then there's not enough oil in the engine and could cause the engine to sieze which would require a complete rebuild or new engine. Get a gallon jug of oil and pour some into the oil filler hole and after a little at a time check the dipstick to see if any is on it and keep going until it is seen. Another thing to try is if you have any friends that have the same vehicle with same engine in it try using their dipstick to make sure the one you have isn't to short causing the oil not to be seen. Once you get the oil level to the right place then get it started and let the engine run for a while to make sure the oil has time to circulate and re lube the engine if it was out of oil. As for the coolant leak if you haven't already replaced the water pump then when you do so replace the upper and lower radiator hose and hose clamps to prevent any hose failure as well.

Mine stopped leaking coolant when I stopped filling rad to top of neck. I leave level few inches below to mimimize pressure build up on gaskets, hoses, clamps.

You figure out if right dipstick and where oil going ?

well i put 5 qts in the engine still no oil on the stick and its not leaking into coolant or on ground, plus now it seems it wont start because my fuel pumps not turning on. I just give up at this point probubly just sell it as parts. since fixing all the problems will be more then i paid for the blazer.

If you put 5 quarts in it and its not leaking onto the ground then you have a magical engine. The oil is going somewhere, 5 quarts is more than enought to show up on the dipstick. Not to be condescending but are you checking the right dipstick?

Even the transmission would be way too full now, I'm kinda wondering if the dipstick is broken off somehow.

Unless the oil is crystal clear, and you just can't see it on the stick, try wiping it off and seeing if the rag is full of oil

yes i am checking the right dipstick. No its not broken off. As for wiping it off there isnt even sludge to wipe off its bone dry. This ones got me scratchin my head big time. And with the truck not starting now due to a mysterious fuel problem as well i just about give up messing with it. it would be cheaper to buy a new one then take it to a garage+.

well here is some hope it has a fuelpump shut off if oil pressure is to low you need to disconnect the batery for about ten min to reset that since it happened before you could get it to start but the oil problem is a different thing look inside your valve cover and see if oil is standing in it maybe a stupped up drain back I had that problem with a 4.3 monte carlo that had been run hot a few times maybe this would help

thanx for the idea ill try disconnectin the battery tonight and see if it will reset. as for the oil i figured it was going some where in the block. i know it wasnt leaking and thier is no way i burned up oil that fast. i didnt run it hot very long only a few miles or so. im ussually good with my vehicles. Although it doesnt help that the previous owner let it sit for long periods of time so its pretty rotten under neath. i was expectiong it to fall apart before the engine stopped runnin lol

Wow ... this one is interesting ....

Get under the truck and drain the oil pan ... how much comes out ?????

well update,
my dipstick now lies pulled the oil plug and like 8 qts came out so im goos there. Now it just comes down to why when i refilled my radiator did the truck stop getting fuel? im pretty sure that the fuel pump is not running so i guess i have to check the wires. Also does anyone know what the proper oil pressure is my gague reads like 20 after i cranked the engine for a minute. thanx

I can't answer any of your questions, but I will sugest that you add the corect amount of oil and add a new line to your dipstick (if you can see it on the dip stick) The line is never really in the right place anyways.

Does anyone know where the fuel pump relay is located on a 1994 chevy s10 blazer with the 4.3l? thought id check that next

ok well that bring me to the next one a fuel pump has probally failed
the relay on the older ones are on firewall right at the brake booster normally 3 small black relays and the closest one to the driver's side is you but a fuel pump is probally your fix generally 40-80 bucks and a friend to help set the bed off is the easiest way I did mine in about 2 hours and it was about 6 months ago it just quick no warning at all drove it shut down 5 min later tried to crank and nothing

whoa whoa whoa. first off, either your dipstick TUBE is broke and the stick is sliding out of it somewhere not inside the engine, or the stick isn't for that truck, possibly outta something else.
Secondly, you should be able to hear your fuel pump run for a couple of seconds when you turn on the ignition. get someone else to turn the key on (not turn it over) while you are down by the gas tank, listening. If you don't hear it, run a jumper wire from the relay by the firewall, down to your battery. (negative post i think, you can try either post just not at the same time) If, after doing that, you still can't hear the fuel pump kick in, it's prolly time to drop your tank and change the pump.

Oh, I forgot; dump all the oil outta that engine and replace it with 4 1/2 - 5 litres, cause if you have too much in and that thing does start up, you are gonna blow seals outta that engine from too much oil pressure. I know a guy (who's far from a genius) who checked his oil once, he was down a litre, so he buys a gallon, thinking it was down a bottle of oil (i assume) he dumps in the whole gallon. Well he blew his seals, lost his oil, then his engine.

blowing out the seals is the lucky way to go, the crank slapping the oil airaids it, which can cause a lack of lubracating problem

yeah i put 41/2 qts in after i drained it. im gonna try to jump the relay as soon as i can of course its pouring rain outside right now :( . i just hope that is the pump i cant afford to replace that now. as for the dip stick i know this sounds wierd but it doesnt look thsame now that i look at it. i have no clue why some one would switch them but i did have it it the shop recently for a tune up. maybe they lost mine and stuck another in? i know it sounds far fetched but it does seem a bit short for my engine, and i have checked my oil before obviously w/out there being a prob. I am a bit distrustfull of shops thats why i always fix my own stuff if possible. Not to mention im poor and it ended up costing me a few hundred for new plug rotor, cap, and wires, plus it took them a week almost. but it was too cold outside and i dont have a garage so i had to let them due it .

Well .... I think everyone deserves a big "DUH" for not thinking about the obvious dip-stick length. I know I do .....

Hey, in my second response (#9) I mentioned that the dipstick might be broken. :nono:

Doesn't that count for something :grinno:
LOL

i believe in my first post (#17) i siad that that stick is possibly NOT for that truck. but a big DUH to ya for not reading all the posts fully.

also i'm curious as to how blowing your seals is the lucky way to go. (dmbrisket 51's post # 19 ) if you blow your seals and not catch it right away, you are gonna lose most if not all your oil and seize the engine. what else could possibly happen, as a result of too much oil in the engine, that would be worse than that?
