engine died while driving and wouldnt restart why?
Asked by Timhill Apr 03, 2012 at 07:03 PM about the 1994 Chevrolet Suburban C1500 RWD
Question type: Maintenance & Repair
I have a 1994 suburban 1500 2wd 5.7L engine with 63000 miles (yes only 63000 miles). Yesterday as i was driving the engine just quite and would not restart. After having it towed to my house I tried it again this morning and it started fine and ran the whole day without a problem. The local mechanics tell me that they cant diagnose and fix unless it is actually in a not start condition. What could be the problem?

There is no way to tell what happened. If it does it again. Try to narrow it down to an ignition problem or a fuel supply related problem. That's the best you can do for now.
Fuel pumps will fail intermittently sometimes at first before they finally quit, so borrow a fuel pressure tester from an auto parts store and look up what pressure is specified for your vehicle and replace if too low.

HELP!! I am having the same issue and also have just replaced the fuel pump (no filter though) .... has anyone figured this out? My steering column is also super loose ... could this be related?
I just had mine die while running 40. Wouldn’t start wouldn’t crank wouldn’t do anything come to find out the starter relay somehow came loose and my battery drained

I changed my computer and it has not done it again
Mine does it but stays back, does a few more times, and then drives good. Filter has been changed, black box replaced, sensor replaced. Any ideas anyone?
The crank shaft positioning sensor. My 2002 Suburban would drive fine and then just die without warning. After about an hour or so, it would start up with no problem and drive fine. Sometimes it would go for a week or just 5 miles and die again. I had the fuel pump changed and still the problem continued. I finally read about the crankshaft positioning sensor fouling out causing he computer to think its overheating — causing the engine to shut off for protection. I replaced it and everything has been working perfectly. It’s a $99 part, and took about an hour to replace myself.

1999 Suburban 5.7 8 I had the same issue and the cause was ignition control module. Usually my car would spit and sputter then just die. After doing some research the module was the cause. They will work fine until they get hot and then fail. Don’t buy the cheap $10 ones on internet, new part is $75 - $100 OEM.
