My 1999 gmc suburban runs for a couple of seconds the dies. There are no codes, fuel pressure is 60 psi when I turn the key to the on posistion, then drops to 56 psi when the pump kicks out. There is no security warning I disconnected the crankshaft sensor then it would'nt fire at all. Someone thinks its a malfunctioning pressure regulator.
