Car wont start, unknown problems.

[Shadowofoblivio]

Note: For all of those who read and dont have any ideas whats wrong this thread will be updated with new information as i find it out.



Last night while driving home the car started acting as though it had no power, wouldnt go past 4,000rpm, and would bog down. when i left it started and drove jsut fine the whole night. Once it started doing this i pulled off an offramp close to home and it died on me at the stop and wouldnt turn back on. Got a ride home got some tools and headed back out.

Pulled the spark plughs and they didnt smell of gas or anything. all 4 pistons have spark, the timing belt is still there and in time, the pistons are dry, it wasnt smoking, and it appeared to be getting gas.

Towed it home and today i started looking more in depth to it. i ended up only finding one thing wrong, when a noid light was put into the injector plugs and guess what.... nothing. checked with a volt meter....... nothing. i played around a bit and the only way to get any voltage to show was ground the negative to the batt and on both terminals it shows + power, one battery voltage and one a little less. i pulled the ECU and cracked it open and found........... nothing. still fresh as it was off the factory.



my guess since that all 4 are doing the same thing that something inline where all 4 injectors are connected to/ and or controlled by went bad. what are the components in line with the injector circut and what all could be the cause of this?

Thanks for reading, and all help is appreciated.

 

[dsm mad man]

yea im having sumwhat the same prob, did you check the ECM

 

[dsm mad man]

did you check the ECM. it controles the injectors. when you turn the key on and right befor it starts can you heir the fule pump?

 

[Shadowofoblivio]

yes i checked the ECM. i pulled it out looked at the board. no shorts no discoloration caps are perfect. the fuel pump turns on and is pumping.

 

[Shadowofoblivio]

well i found out that the injectors actually are working. the fuel pump is pumping but im not sure how much psi.

i sprayed carb cleaner in all 4 pistons through the spark plug holes and guess what... it started and stayed running and didnt seem like it was having problems. i turned it off because i had to tighten up a connection on the alternator then it wouldnt start again.

anyone have an idea what this problem is? i need to get this fixed by tomorrow so please help. thanks

 

[Shadowofoblivio]

After a cople hours of adjusting and checking i got it to start and run, but now other problems have revealed themselves.

1. it doesnt want to start right up it takes a while and sometimes wont.

2. it has a really loud noise coming from the exhause cam area. the noise isnt like anything ive heard before and is sorta hard to describe, almost like a spun bearing but
squishy sounding.

i re did the timing and it is perfect now. before i had to keep it one tooth off because otherwise it would lack power and vibrate severely.

good news is i found it early enough to actually not damage the crank, but im not so sure on the connecting rod. this sucks because it was just rebuilt 514 miles ago and im very very low on money.

and im off like the flash to see how much this is gonna cost to repair. have a good day everyone.

 

[huafist]

Holy shit!
514 miles?!?! Who rebuilt the engine, garden gnomes?

 

[Shadowofoblivio]

well after some lenghty hours yesterday and allot of work i got the engine back together. the connecting rod was in good enough shape to use it just had some discoloration and visible blemishes .

i got everything back together and it still wouldnt start. eventually i got it to start and i let it run for a little bit. after about 5 minutes i turned it off, everything was normal, but it wouldnt start back up .

so i get up this morning walk outside try to start the car and it starts right up WTF . it seemed fine so i took it for a quick drive around the block, when i got to the stop at the end of my block coming back it died. took a lil bit to start back up but it did. got it back to the house pulled it into the driveway and it wouldnt idle and stay running without me pressing the gas. i let it die and then tried to start it back up but nothing. it cranks and acts like it wants to start but it just doesnt have enough of something.

so what would cause this?

 

[Shadowofoblivio]

Holy shit!
514 miles?!?! Who rebuilt the engine, garden gnomes?

i really don't see the relevance of who rebuilt it because it seemes that it wasn't the process but more of something else that led to it. but alas it might as well have been garden gnomes.

It's relevant because 95% of the time a failure that soon after a rebuild is an assembly problem.

true, but since i was the one who rebuilt it i know that it was assembled properly. that is why i think it was something else that led to the problem and also because im still having problem that arent directly related to that. but who knows i might have effed it up during install but oh well.

anyways, got any ideas why it wont warm start anybody?

 

[Shadowofoblivio]

well i might have a possible lead to follow. the CAS might be the cause of this but i dont have time to check it right now

anyone else think that a faulty CAS could cause this?

 

[rollingrust]

I'm leaning toward your ISC.

 

[Shadowofoblivio]

Well now i have changed the ISC, TPS, and CAS but it still does it.

i could walk out there after leting it sit for the night and it will start up, it will stay running for about 3-5 mins until its warmed up then it will pretty much forget how to idle. if i let it die it wont start up again until i let it sit overnight.

It does make the sound like the injectors are shorting out but only when it is at a really low idle and about to die.

Anyone got any ideas?

 

[Shadowofoblivio]

so nobody knows or has any ideas about what is wrong with the car?

I dont know your problem but i am working on a 2nd gen doing the exact same thing!!!!!!! over night it will crank but once it does no luck geting it to crank again. Machanic shops say it sounds like a map sensor problem. So i was wondering what is the equivilant to a map on this car?????????? Please help

the MAS, the big ass black canister that hold the air filter.

my problem is getting good spark, definately getting fuel because it is SOAKING the freaking plugs...

ok, changed the fuel filter yesterday and it does the exact same thing no change whatsoever. my brother took a look at it and thinks it could be the fuel pump, what does anyone else think?

 

[Bostedquest]

what is your pressure now?
That is the only way to really know, without having to spend 100 plus... on something that is not bad.

 

[Shadowofoblivio]

not sure on the pressure right now, but after i finished the rebuild it was at 55psi while cranking and would hold at 48 i belive.

i dont have a fuel pressure tester but i will go get one tomorrow and test to see.

well I have adjusted mine everywhere from 28-30 up to 40-42 and still will not start...
everyone says, 34-36... (anoying buzzer noise) wrong... soaked plugs.
so I took it as low as I could get it, 30 -or a little under (insert annoying buzzer noise) wrong, still nothing.
I even tried starting fluid... (insert buzzer noise) wrong... still nothing...

SO I quess I am down to a coil, or a starter because I still cannot get someone to answer my question about what speed should the starter be spining the engine... Right now it is not going above 200-225 (at the absolute most) usually around 170-190... According to my SAFC2 at least...

I would think it would need to be a little quicker... usually I thought it was 1/3 of idle speed at least... 250-270 or so...

Ive seen starters spin at 1/6 of engine speed and crank a vehicle. My suggestion is to try the coil replacement. If you have a bad ignition coil, it will start the car, but diminish as it builds heat. Engine temp might not determine how quick it dies but might affect it at the same time. Usually, coils will work until they build their own internal heat and then start to die from there. Engine heat just accelerates the problem. Check the coils and let us know what you find.
