Question
start perfect 1st thing in mooring after shut off wait 1-2 hrs hard to start check fuelpressure at fuelrail it was 52psi and watch it go down to some times 20psi can u help pls walt

Answer
Hi Walt,
The fuel pressure sounds good.
The leaking down wouldn't concern me, as long as it stays up while you are cranking the engine, or while it is running.
If it drops while it is doing those things, change the filter.

I am tempted to think you may have a bad coolant temperature sensor. read this. http://www.chevytalk.org/threads/showflat.php?Cat=0&Number=1685353&an=0&page=0#P...
