Question about 1999 Chevrolet Blazer
Got a 1999 chevy blazer. 4.3 v6 vortex. Once its started it will start fine. But after sitting a few hours it won't start. Its not getting fuel. If I pour gas into throutle body it will start and drive fine . When running it drives fine not slugish or anything. I put a fuel pressure test on valve on fuel rail were it goes to test it. It should read 60 to 66psi. But it read 56psi . And continoued to drop pressure very slowly once done . Since it is low does that mean fuel pump is bad or fuel pressure regolater.How do i test fuel pressure regulator.Not sure fuel pump or fuel pressure regulator. Already checked fuel lines fuel filter all good.
Probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold
