95 eclipse non turbo wont start..only runs on #4 cylinder!

hey i just got a 95 eclipse..and it almost starts..but wont! ..and the header for the #4 cylinder gets warm only the others are cold...i have spark and compression on all cylinder..fuel also in all cylinders..i am totally stumped as to what it can be!! i dont really know these cars well so any help woul dbe great! thank you!:banghead:

I'm guessing since you said it has a header that this is a non-turbo 95 eclipse correct?

Also, Welcome to AF. You posted in the wrong forums, this should go into the problem diagnosis section for future reference. I am sure a mod will move it as soon as they see it.

Also provide a bit more detail on your problem like the make and model of car. Also you said you have compression, do you have good compression? What does the car do when you try to start it?

Try to be as descriptive as possibile (About your car troubles) in your posts when asking for help. It will only serve to get you help faster by us not having to ask you several routine questions.

it is the 2.0 non turbo 5 speed. compression was all bout 170ish

its almost starts then thats it..just on the #4 cylinder.

and i just did my engine codes and the ones that came up are..

12
43
42
41
11
54

the car has a new computer also from mitsubishi so its not that!..i really dont know what it is..i just got the car like this..was hoping to get it running! anyone know what the deal is? thanks

check your firing order and make sure your timing belt didnt skip

the firing order is good..kinda hard to get that wrong? and the timing belt is new..and i have the cover off so i already checked all the timing marks and they are all perfect..i am stumped!! :banghead: :banghead: :banghead:

*EDIT* After looking into it a little more, half of those codes I posted were incorrect and some of them don't even come up on the diagram. Are you sure you counted them correctly? Try doing it one more time, these are the only ones I found though.

Code 12 - Direct battery input to controller disconnected within the last 50 ignition key-on cycles. (Disregard this code. It has no effect on the performance of the vehicle.)
Code 43 - Ignition Coil No.1 Primary Circuit Failure
Code 42 - Ignition Coil No. 2 Primary Circuit Failure
Code 41 - ?
Code 11 - ?
Code 54 - ?

thanks but what does all that mean???

I'll post up what it means and how to check them at about 630. I'm in class and have a study group after so I won't have time to piece all of it together. Try searching some of it, I'm pretty sure you should be able to find most if not all of your answers.

i been messin with it a litte bit so it runs on #1 and #4 so i figured that it was the coil pack!! so i went and got another one..and nothing!! they all 4 spark..but some spark way brighter then some...any ideas would be freakin sweet

Sounds shorta what my old 1992 Eagle Talon was doing. We changed the fuel pump, coil pack ect ect. Turned out to be the ECU. Try that.

ECU is brand new from mitsubishi...but i can maybe find one in a wrecking yard and give it a shot..but i dont know..been working on the car for 3 days and cant figure it out at all!! never een this confused...i was told by someone it could be the electronic ignition? does this have one of those!?

Let's try to figure out exactly what's wrong with it before you go and start buyin random parts for it hoping it fixes the problem. What i'm gathering is that it sparks on all 4, but #1 and #4 spark much brighter than #2 and #3? It's definitely an igniton problem, but doesn't involve the coil itself. You say the ECU came directly from Mitsu, and you're positive it's the right one? 95-96 ECU's differ from the 97-99 ECU, and I know especially for the 95's that you need the exact ECU that came out of the car, maybe that's your problem. Can you pull the ECU and take a picture of the numbers on it and post the pic on here? I'll see if they coincide with the ECU from my 95.

Are you sure your plug wires are going to the right plugs? Not too hard to get them on the wrong one and if you are sparking, have fuel, compression, and all that other jazz its something small and easily looked over.

its brand new from mountain mitsubishi... the numbers on it are


1-R5013113AA

its about a week old!

1 goes to one
2 goes to 2
3 goes to 3
4 goes to 4

thast left to right 1-4 correct?

From left to right it's 1-2-3-4.

On the coil they're numbered as:
1 3
2 4

also the car has a new cylinder head..i dont know if it was ran after it was installed..is there something that could of been done wrong?

1 goes to one
2 goes to 2
3 goes to 3
4 goes to 4

thast left to right 1-4 correct?

The cylinder closest to the crank is number 1. So on the 420A it should be 1-4 left to right. Did you try some resistance tests on the ignition coil, and spark plug wires? Are the plugs new and gapped correctly?

the plugs are good everything is good i think! its really confusing me i am about to give up!!! probably just sell it broken down! haha

I'll give you 200 bucks for it LOL j/t DONT give up. Its proubly sumtin really stupid.

i figuring its something stupid...or something really bad!!..maybe it has a screwed up cam..? i dunno anything about these ars..im mre of a mustang guy haha

Do the ECU's match up? What about the TBS? Would that have anything to do with it?

i have no clue man....i dont know what to do..all i know is it want to run pretty much only on the #4 cylinder..damn

Havnt figured out how to post yet, but ask this guy.

He seems to know ALOT about eclipse and stuff.

also the car has a new cylinder head..i dont know if it was ran after it was installed..is there something that could of been done wrong?

That shouldn't have anything to do with it. You say you have the timing cover off, that means the whole thing right and not just the little top part? The cam gears need to be aligned, and so does the oil pump sprocket. Have you checked out the crank sensor? A bad crank sensor will cause some funny ignition problems. How about the ignition switch?

When I go home this weekend I'll check that ECU number with mine and see what comes up. I'm guessing it has something to do with not getting enough power to/through the igniton switch via bad wiring, faulty ignition switch, or that the crank sensor has shit the bed and is giving you innacurate readings.

Also do you have a multimeter, or have access to one? I can get a bunch of tests for you to run on a bunch of different sensors to start ruling things out.

the whole timing cover is off..everything is aligned perfect!...how can i test the crank sensor? would it only make it do that shit if it goes out? i thought thwne they go out it doesnt give any spark at all whatsoever...

It's a magnetic sensor, anything could cause it to act weird. I'll get some tests in a little bit when I'm back on my laptop.

if i take the sensor outcan i get it tested somewhere> i tested the wires and they ae goodwith my volt meter...so hopefully thats my problem...i need to get this thing on the road so i can sell it! and dump some money into my supra. haha

Hey man have you made any progress with your issue? i changed the oil pump and put everything back together and car was running and i was starting it, then turnig it off to let the oil pump prime and it stalled out. turned it back on ran and stalled out again. now it wont start at all. Has fuel, spark and ive timed it 4 times and still wont turn over. Im horribly stumped like you so if you can some insight please help.

Are you getting a CEL? That almost sounds like a crank sensor the way it starts up, and then shuts off right after that.

Please start your own thread instead of jacking his. Have you checked the timing since you put it back together? I bet your timing is off.

Welcome to AF.

Well if you look at the post i asked to original poster a question because i figured he would be looking at his own post and would run across it. And yes i have checked the timing 4 times. took off the valve cover and made sure the lock pin didnt break on either of the cams and they spun together with valves opening and closing. and the crank is lined up good too. THats where the confusion is because when you try and start it it sounds like its out off time but its not. had little back fire, all plugs have spark, fuel sprays out the rail and the plugs are wet so fuel it there. lost and confused.

I guess I missed the part in your first post when you said you timed it already. Did you make sure you plugged everything back in when you put it back together? I was thinking maybe crank sensor right away but you said you have spark so that eliminates the crank sensor.

What does your compression look like? Get some numbers for me please.
