Question

Have a 2000 Chevy Tahoe. Owned since new. Approx 3 times a year the engine wont start after it has been running for a while and you shut down to run in the store or shut down for a short period of time. when you come back out, it starts but dies right away. No amount of pumping the accellerator will keep it running when trying to start it or flooded engine procedure works. The only solution is to let the car sit for approx 10 minutes and the car starts up normal. Car starts 99% of the time but those few times it happens makes you wonder if one time it wont start after the 10 min sitting time

Accepted Answer

There are two things that come to mind, and depending on what your SECURITY light does when it won't start, will dictate what it could be.

When it won't start, leave the key in the "on" position and see if the security light is on. If its on, then you may have a PassLock issue (the truck thinks its being stolen).

If the light is NOT on, then you probably have a bad fuel pump.

Reply to GMTechBernard's Post: The security light does not come on. It is not a passlock problem. The problem seems like it may be a heat problem. It happens so infrequently (approx 2-3 times a year) but when it does happen, waiting approx 10 minutes always solves the problem. I have driven the vehicle numerous times for long distances with multiple stops with no problems but when it happens it is a big problem. It is never a problem on the first start of the day. Only iof the car has been running and you shut down for a few minutes

Answer

I would be willing to bet its a fuel pump problem, but the only way to know for sure would be to have a fuel pressure gauge hooked up, while its not starting.
