Hi,My name is Tim,
I will do my best to assist you
what is the year.make and model of the car?
does the engine light stay on?if so,can you give me the computer codes?
It is a 2002, GMC Sierra 2500 HD with 24,000 miles. The engine light stays on, there are NO computer codes or any information in the red light at all. It's as if you just turned the key to accessory mode and the engine stalls.
what is the engine size?
8100 vortec with allison 1000 transmission gas engine
and the service engine light doesnt come on?
this has happened about 10-12 times starting in July and the check engine light came on once. I immediately drove to dealer so they could see that, otherwise nothing has appeared on the dash except the red light
when it dies,,is it as if the key was turned off?
yes, no power brakes or steering and the red light is on. I coast to slow down then pull over and turn on flashers.
how long before it will restart?
usually about 30-60 seconds. one time in the rain it was about 3 minutes
sense you get no trouble codes
and from the way you explain
it sounds as if you may have a bad crank sensor
these will do this sometimes when they go bad
most times not give a code
okay, my neighbor who dabbles in GMC repair suggested this when it first happened back in July. We mentioned it to dealer and they frowned on this, and that's when they said it was the fuel pump which they replaced and obviously didn't fix it. Perhaps I should just tell them to replace it?
they may or may not replace it
im sure they will if you pay them
Tim, they tell me it has to fail while they are driving and that's the only way they can find it. I've told them what I've told you. What do you think?
i think you have a bad crank sensor
Thank you, XXXXX XXXXX will be excellent
you are very welcome
