#1 of 2 fuel pump or pressure regulator by pops1956 Sep 19, 2009 (12:27 pm)
my wifes 2000 blazer had check engine light on. they did some kind of giagnostic on it and said it was a fuel system problem.it was running ok at the time and since they didnt seem to know what the issue was she just ran it. well today it wont start. just turns over .fuel pressure comes up normally at prime but wont hold,drops straight to zero. how do i distinguish between the pump, regulator or something else? thanks.
