My 1988 C20 5.7L TBI 350 full size van won't stay running. It will start and run for about 10 seconds, then die. It won't restart immediately but will after waiting 20 seconds. The cycle repeats itself no matter what steps are taken. Fuel pressure is 9 to 10. Any help or or direction is appreciated.

 

Do you know what the fuel pressure is supposed to be at? I could be wrong but I think it is supposed to be a little higher. How long has it been sense you changed your fuel filter? (more likely it would die after going into gear)
Is your engine light on? It could also be something like a throttle positioning sensor being bad and killing it.
If you can tell us anything else please do, and good luck

 

Looks like we're going to change the fuel pump. Everything else checks out. Thanks for all your help!
