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 LS 2-Door RWD

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??

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!?!?!?
