Re: 1999 Blazer stumble/stall
ok.. did the fuel pressure.. at key on engine off, it immediately jumps to about 65-66psi while the fuel pump does it's 3 second deal, then holds steady at 63 psi. once started (cold start), it goes to about 56 psi and stays there. let it idle for a few minutes, no change, stays at 56. I gave it some gas and it jumped to 60 psi, let off the gas and it dips down to about 50, quickly jumping back to around 56. turned ignition off and it went back to 63 psi. I had thought i was going to do repairs myself, but if it's the fuel pump, like i'm suspecting y'all are going to tell me now with these fuel pressure results, then I'll let someone else do it. I'm a little wary about dealing with the gas tank, plus it should (should!) be covered under warranty. is the fuel pump what it sounds like to y'all?
