died and wont start

[Menacing talon]

I have a 90 Talon Tsi thats pretty much stock except for an exhaust and a boost controller. So I was driving home yesterday after replacing the shifter cables and about 2 minutes from my house I was coming down the hill and I heard kind of a pop and then everything just died. The tach went to 0,all the gauges shut down, but the radio was still playing. I tried popping the clutch seeing as I was doing about 55 MPH,no such luck. Tried turning the key and still no luck. I rolled onto the shoulder and checked distributor wires etc. No problems there, what could make a car die when youre doing 50+ MPH and then not want to restart. When I try to restart the car it will crank but it wont actually catch and turn over,Its like when you do a compression test and unplug the ignition wire and the car will just crank all day. it snowed for the first time here today and my Talon broke last night,Im stuck driving my 73 Nova through the snow so I kind of need to fix this fast if at all possible. I was thinking maybe a timing belt,but I wont be able to check until later today. Sorry for long post

CAS is cam angle sensor. CPS is crank position sensor. And this is a 1g we are talking about which has both integrated into one.

To the original poster, check compression, power transistor, and cas. The coils and ecu rarely go all of a sudden without any warning.

I never said it doesnt happen.


Off topic, maybe you just havent noticed the small signs of future failure with your own car. With you being on your 3rd ecu, I would guess that you either have other problems causing ecu failure or you are just sticking used ecu's in your car without replacing caps prior. I had the stock ecu in my car until it died in late 01-early 02. I had Jeff O repair the ecu, replace the caps, socket the ecu, and supply a custom tune eprom for it. I have yet to have any ecu failures since the rebuild and most others have the same results as me.

I also had an issue exactly like his a few months ago which was a black top cas that pooped the bed while cruising.

Maybe your coil packs are shot,have you tested them?

I don't know how to check my coil packs. How do you test them?

Exactly. That's why I linked to that specific post (and not the whole thread). But if you're feeling lazy, just look at the above post as it's the same image.

I figured that much =]........And its not my coil pack because I bought a new one.

What else could it be besides the coil pack ??

 

[vinnio]

I bought a new balloon but it went flat after a week.

If you didn’t catch that, what I mean is just because its new doesn’t mean it works right (or at all). I'd check it anyway.

Lol, You had me like word !...hehe...

Well i kno it work's because i tried it on my friends GST and it turned on....

Anyone else have any conclusion's ?

Did anything change when you put the new coil pack on? Are you getting any spark now?

Negative.....No spark. =[

 

[1gTurboTuner]

To the origional poster, I've had no spark problems before and an easy way I found to check if your ecu is the problem is to turn your key to the on position and see if the ecu light come on in your gauge cluster. If it comes on the ecu is ok.

With my experience I tried everything and the car wouldnt start (no spark!) then i found this ecu/key trick on vfaq I think? And the ecu light wasnt coming on so I swapped in a new ecu and she fired up.

Good luck,
Allan

Put your power transistor in your friends car and see if it works on his car.

Power transistor ??....You mean the plug that's next to the coil packs ?

Yo Sax!! Power transistor. Isn't the problem either both of my things turn on, on my friends car.

Anything else ?

You said you just rebuilt your engine. Have you had it started since you put the rebuilt one in? Did you rebuild your stock engine or did you do a 6 bolt swap? Are you sure you have every connector, power wire, ground wire, etc. hooked up?

I rebuilt the stock 7 bolt motor. I rebuilt the engine about a year ago. I was just driving my girlfriend home and my car just turned off. I tried popping the clutch while I was still moving and nothing....Today i checked my ECU and there was 2 loose cables. I welded them back together. Every connection is intact.

His motor was rebuilt months ago.

How do you know that you're not getting spark?

My friends told me. And the mechanic told me.

Check for yourself, just to make sure we're not running in circles here.

Before checking for spark, first remove and inspect your spark plugs. Are they improperly gapped or have they been fouled by age, improper fuel mixture, etf? If so, replace them and try to start the car again.

To check for spark, disconnect one of the spark plug wires and attach a spare spark plug (it’s always good to have a spare handy – you can use a cheap-o one from Wal-Mart for testing purposes). Place the plug and plug wire onto the valve cover and have a friend crank the car. Do you see spark arcing onto the valve cover? Sometimes it’s best to do this test at night – this makes it easier to see the spark. Repeat this test on all 4 cylinders to verify that you’re getting spark all the way across. If you’re not getting spark on some or all of the cylinders, first check the condition of the spark plug wires – does the spark try to arc through the wire while you’re testing? If so, the wires are damaged and must be replaced. Next, check resistance at the coil. Specs differ by year, so refer to your FSM for the specs for your particular vehicle. If everything tests out okay and you’re still not getting spark, pull the ECU and check the board for damage due to capacitor leakage. DSMs are not getting any younger, and are notorious for leaking ECU capacitors. One final culprit could be the CAS. These differ by year as well, so again, refer to FSM for appropriate testing procedure and specifications. First, however, you might want to make sure the CAS is not turned 180* out (i.e. “on backwards!”).

The other day the CEL was coming on when I turned the key over,I checked yesterday and now all of a sudden,no CEL. I guess my ECU is fried,Now its time to search and find a known-to-work 90 ECU so I can get my damn thing running again

 

[gsttuner22]

For some reason or another i think it's my spark plugs, starter relay, and alternator fuse....

Spark plugs = ancient......

What plugs should i go to next ?

Starter relay - Because the same night that the car turned off. There was like a buzzing noise coming from from that box which i know now was the starter relay.

Alternator fuse - I used to have battery problems, and alternator problems...And never bothered to check the fuse.
