Starting issues - No / Doesn't / Won't Start - MERGED

[prodsm]

All "my car won't start" discussion threads are merged HERE. We've basically made it easier for those who insist upon not searching by grouping together all threads from those with similar issues so you can just scroll through and see some possible solutions. To search for info within this thread, use the "Search This Thread" feature in the black bar about 3" above what you're reading right now.

Could be anything from a loose battery terminal to internal engine damage, and literally everything in between which may involve the electrical, fuel, and ignition system...possibly even something that you screwed up while working on the car yourself. While it's unlikely we're going to diagnose and solve your problem over the internet, feel free to discuss any possible solutions.



I live in Canada and right now its not very warm out, about -30c
my car does not have a block heater too keep it warm.

I tryed to start my car this morning and it wouldent start, ive had this problem before but this time, the car doesnt crank at all it just makes a sound that sounds like an electric drill.

Whats wrong.

Thanks

Also, after reading those articles, I'm becoming more worried because I definitely had a ticking sound that I thought was lifter tick but another member who was at autocross with me didn't think it was lifter tick.

That member was me.

Jordan, im surprised this idea didn't pop into my head that day. It does kind of all make sense now.

When measuring, IIRC, within spec, play should be in the 0.0080" - 0.0040" range. Someone correct me if im wrong.



Not being to familiar with CW, but Jordan was also having blow-by issues. Oil was coming out of the dipstick tube and from between the head and Exhaust Manifold. The car ran its best when the Oil Cap was not on. He had none of these issues during that run. (IIRC)
Would CW have anything to do with that? I'm assuming it would be hard to diagnose, as CW can cause all kinds of problems.

Yes I forgot to mention the blowby. I have a two-catch can setup. I catch can between VC going to can and a hose off can to the intake pipe. The other one goes from stock pcv to can and a line from the can into a U.S. Plastics check valve (pointing in correct direction) and going to IM. This can had oil and nasty crap in it when I checked. The one between VC and intake pipe was bone dry!

On another note, I just went out and tested movement on my crank pulley. I moved it as far as I could to the tranny side and then pryed on it towards the timing side. I had an extension in the bolt hole to watch it move against the framerail and I was able to move it about 1/8th inch. That was the crank bolt itself, not the pulley outside the rubber part of the pulley. Is this bad?

hey guys would leaking caps blown the MPI fuse by the battery ?

heres the best i can get with my phone, yes all the lights come on and after 5 seconds the engine and seatbelt light go off

from what i can tell i dont see anything wrong with my ecu. i have power going to the starter and the grounds are intact. all my fuses are good as well, i dont really know where to look next.

i think it would just idle high if the isc was unplugged while running. id check the voltage to the isc and see whats going there. watch this vid here to see that done [ame=http://youtu.be/KibYz21IMA0]DSM ISC motor testing & Replacement - YouTube[/ame]

I zoomed in on that pic, didnt seem to have blown/bulged caps from what i can see in the pic. does the starter click when you turn the key? or does the engine crank? if the engine cranks do you have spark and fuel delivery? check those first and report back.

everything ended up testing good when i was going through everything. it ended up be a broken coolant temperature wire. thanks for all the input though!

Not really sure what's tolerable but don't think it's supposed to move much at all.

 

[oldman_tau]

do you have all the lights,power windows down etc? might be starter?

glad to hear you got it under control.

Great.

There is some slight leakage from them and you can see a bit of corrosion from this as well.

Doesn't look like it would take much to clean up and those some new caps in(hard to tell from the pic but those look old(at least the lower 100µF one) and a few new points resoldered.

It would be Good piece of mind regardless... .

After Tearing apart the harness i found out that there is a break somewhere in the harness that goes to the coolent or cam angle sensor, I hope that this is it!

 

[NoHndlbrsRqrd]

That sure sounds hopeful!

I was wondering what you were tapping into the ECU for. You mentioned that in your first post.

 

[ChrisMgst]

How long have you had ECMLink v3? Can you connect to link and upload a log?
Did you swap plug wires yet?

[BurrowZ]

Using a 95 ecu with a 1G cas will cause problems.Read the post above mine.

 

[synthetek]

For your no cranking problem make sure this plug is connected http://www.dsmtuners.com/forums/151542290-post41.html

Driving the car and was running fine, I had a weak lower radiator hose and it blew. Turned the car off immediately. Fixed the hose and replaced the thermostat with the lowest temperate one I could find. Went to start the car back up and was idling really rough like it was misfiring. Got new plugs and wires does the same thing. The next day I go out to look at it and it won't even start, just turns over and sometimes one of the cylinders will fire but won't start. Replaced the coil pack, ECU, and transistor. Nothing helped. Even replaced my maf and maft cause I thought they might have gone bad from being coated in coolant. I'm lost right now. It's a freshly built engine with 120 miles on it and I haven't had one problem until now with it.

 

[jakeb2011]

First off throwing parts is a guessing game. Narrow it down to fuel, spark or compression. Its mostly likely one of the first two. Check fuel rail pressure and check individual spark. Could be something odd like timing that you can't rule out till checked. Sounds like it could be a weak fuel pump but there's not enough info to tell you anything for sure.

 

[TSI_AWD_FTW]

There is a newer 255 fuel pump in it, also it's getting good spark. I checked all of that, not fuel pressure though. And timing is what I was going to look at tomorrow to make sure it didn't jump a tooth and also I'm going to check out the CAS to see if that's all good. I'm just needing extra advice while I trouble shoot all of the obvious stuff.

 

[Nathanxavierr]

Tapping a crappy Narrow Band into the 02 Wire, i trashed it now and just ordered a AEM wideband. Like I fixed all the problems i got spark now and the motor tries to start now. but now runs like complete shit then dies 4 seconds later anything else could be the problem?

Rough Idle 4g63 Bad timing? - YouTube

i finally got her running but now i ran into another problem ughh.

 

[Turbomaniac18]

Which wire did you fix? I am having a problem with my car not wanting to start it has spark and gas but it just turns over. And will not start it just back fires every once in awhile. I put a new computer in it the old one was bad so if u could tell me what wire u fixed it would be must appreciated.

 

[nodoze]

did you check the back side of the board? sometime the damage can only be seen back their .

 

[Turbomaniac18]

The old computer was damaged. But I bought a new and this one is fine

 

[Nathanxavierr]

With Everything i went through the past two weeks i finally got her running back to normal and she runs great the problems i had with all of this starting in order for anyone that may run into a problem like this in the future was

1.) Coolent Temperature Sensor was the first problem, the wiring had gotten old and it broke off so i had to re- tap the wires make then all nice nice.

2.) The Cam Angle Sensor was the next thing i found out that had Problems the wires broke lose and fried the sensor so i needed to replace it.

With those two things taking care of i had spark problem unfortunately i ran into another being bad timing and rough idle. I then timed the car correctly and it then wouldnt want to generate any spark. after an hour of thinking i tried out flipping the disc in the new cam angle sensor and guess what it started all right up nice nice no problems no backfire No Nada. With Thus being said, Check those discs in the cam angle sensors guys.

 

[nodoze]

have you checked your timing? if you put a new good computer in it and it wont start line up the cams and take a peak, also did your tps get unplugged? but the backfiring sound like a timing issue

 

[Turbomaniac18]

Thats the first thing i checked i mean i put in new lifter and everything. It is in timei know it is i mean it turns over and gets spark and i pull the spark plug and it smells like gas coud it be the ics? What does the ics do?
