2004 blazer. When cold after sitting over night, it floods and will hardly start if at all. Injector crab is about 3years old, tune up and fuel pump is 2 years old.


Asked by Jun 21, 2014 at 10:42 AM about the 2004 Chevrolet Blazer 2 Door LS

Question type: Maintenance & Repair

Fuel pressure is 62 while pump runs,
after pump quits, 58 and bleeds off
quick. Once it starts, it holds 58 and
jumps 5 psi when ya gag it, and fires
easy all day, just does this after it sits
over night. I'm thinking regulator. Any
more input??

Yes,regulator sound,s like good guess,losing pressure.

Hoping I was heading the right direction before I tore into it. To many high dollar parts to try and trouble shoot. Thanks!


Changed the fuel regulator and still have same issue. I guess I have an injector bleeding off. Only thing left I can think of!?!?!?
