95gst died tonite

[96awdgsx]

ME a my friend were driving back home today when his car just died in the middle of the road. It wouldnt start back on. We hear the starter but its not cranking over. It was working ok 10 min before. What could this be?

timing belt.......... :lol:


o0o how we love our engines held together by rubber

Crankwalk took out the crank sensor?

Sorry, just wanted to add to the good news.

Could just be the fuel pump. Could be anything. What have you tested so far?

Please tell me your alternator didnt just crap out. Always try the most simple things first.

[gvr4737]

nope... u gotta always think for the worst with dsm's...

than the pain of a blown engine isnt soo hard to swallow

But would the car just die while its running if the alternator crapped out? I was under the impression that the car would keep running and then once shut off, then it wouldnt start back up. Im not sure what hes tried yet, the car is sitting at some side street in the ironbound section of Newark :shock: Anyways, any ideas on what else we can check? how do you check if it the fuel pump was the culprit? Also, how do we know f it was the dreaded crankwalk? the car does have high mileage. The car has recently had its timing belt changed. Maybe that place did the timing wrong and it was skipping teeth>? IF the timing belt went, does this def mean bent valves and possibly destroyed motor?

If it was the alt it would die completely.. You wouldn't have anymore power because the battery would be depleted at that point.
When you turn the key to on do you here the fuel pump?
Pop the timing belt cover off.. you should be able to see if its skipped or not..
Do you have a datalogger ?

Calm down, it could very easily just be the alternator. If it died, the car could still run for a little while until the battery runs outta juice, which can happen at any time(even while driving).

And also, get that fuckin thing towed! Are you fuckin retarded leaving it on the side of the road in Newark? What are you waiting for?

* IF the timing belt went, does this def mean bent valves and possibly destroyed motor?*

im just a negitive nancy... its probably not a timing belt... with dsm's its always the dumb shit that makes our cars break down...turn the car on and listen for the fuel pump... also if the alternator went it would of felt like it was losing power... not just died.. soo did it feel sluggish and dimmed lights???
it could also be something as dumb as a ground.. ive had it happen before and it was a bad ground wire.. theirs like 10 things to check whenever a car dies suddenly.. but take off the timing belt cover to save yourself some pain..

but yeah.. if the belt went or it skipped a tooth, you have a 99.7% chance that it ruined the motor... soo odds are it did... unless u are that .3% .. like me :D

my car has died for no reason while driving also.

it was one of the fusible links in the engine bay.. make sure you check those.. i believe it was a 30A that blew

You have that backwards, when the battery is dead and wont charge you can keep driving the car as long as you want (running off the alternator) and then when you shut it off it wont restart. When the alt dies and you're running off the battery everything electrical will start to die slowly. First your headlights get dim, then your stereo starts to fade. When you have about 3 minutes of driving (assuming your lights and radio are off at this point) you wont have enough power for the gauge cluster and all the needles drop to zero. Then it starts misfiring and in about 2 min wont run at all. Its shocking how much the coils can do with so little power.

Anyway, the car turns over but wont start. That means your battery is fine, and the car would run off that anyway even without the alt. So forget about your alt being dead, thats not it. For the car to fire you need spark, you need fuel, and you need compression (sealing headgasket rings and valves). You said the motor turns over but wont catch/fire, so we know your battery and starter are ok.

Testing spark is easiest: remove one spark plug, put the wire back on it, and hold the business end next to you cam cover (make sure your hand in on the wire or insolated park of the plug). Have someone try and start the car. You should get a nice SNAP SNAP SNAP spark between the plug and the cam cover. It should be strong and in a good rhythem. If not its probably the ECU signal to the coils to fire. Could be any sensor or power or ground the ECU depends on (crank, cam, ground, loose plug). If a coil went bad, you'd be running on 2 cyl so thats not likely.

If spark is ok, make sure you're getting fuel. Does the fuel pump make a noise when you try to start the car? This would be easy to tell with a Walbro but hard with an OEM quiet pump. Take off the fuel return hose off the refulator on the end of the fuel rail. try to start the car for a second. If fuel blasts out of it, you have fuel pressure. If not your pump is bad or the wiring to it.

Is those are ok, maybe you have no compression and the fuel is just burning up without doing anything. If you blew all 4 piston rings, you would have known it. If the headgasket blew enough that you have full compression leakage in all 4, you would have known it. So its likely the head. Is the timing belt still on? Cams still spinning?

i dont think any of these situations matter, its most likely already stolen.
