1995 Blazer 4.3 V~6: runs when u dump fuel down fuel plenum but dies and wont restart. sometimes will start with key but dies shortly after. fuel pressure 60~lbs all new fuel filters & pump strainer & freshly cleaned tank. Could it be pressure regulator?


Cleaned tank, new pump valve vent, new pump filter & new inline filter, and new gas strainer. maintains 60~psi on fuel test gauge at tester while running.... good spark... wondering what it could be? its throwing no codes on the snap on computer diagnostics? Only runs for a moment dies and wont restart without pouring raw gas down fuel plenum. Help :-)

Recheck the fuel pressure and also check the fuel pump relay and the fuel pump and oil pressure sending unit-
