When it doesn't start what are you missing, spark or fuel?

[steveofwisconsin]

I have both spark and fuel. it starts fine it quits only after engine gets hot.

Right, when your engine gets hot, stalls, and won't start - what are you missing Spark or fuel?

hi i have replaced some hoses that were badly in need from the air clearner to the oil/sir separtor to the oil pan. the spark or fuel will be hard to deteck because it starts up right after it quits. but will check and get back to you. Might take some time.

I guess I misunderstood you?

If you let it idle in the drive way will it stall? If you can figure out how to duplicate the symptom in the driveway it will make it a lot easier to see whats going on.

hi i let it idle in the driveway for 30 minutes no problem but heard clunk sound when pressing gas pedal around the 30 minutes so i turn it off. the sound does not happen before that? and then it quits shotley after.

Check your fuel pressure. GM fuel pumps get weak and will start to sputter out when they warm up and work fine for a while when cool. It should be at around 47-55 psi.
