I got a question my 96 Blazer with the 4.3 Vortec had trouble starting when it was cold now it won`t start at all, I replaced the fuel pump and filter and it ran good then when this wind and cold spell hit us here in Cali, it won`t start wants to turn over but it`s a no go, could it be the fuel pressure regulator? or that fuel injector spider thing i think they call it?, Oh and before i forget after i replaced the fuel pump my gas gauge don`t work Thanks for any info

 

I had the same issue with my 2003 Blazer would run to the store and come out a half hour later and same thing....................ended up being a dirty throttle body...removed it and cleaned all carbon off...............this worked.

 

Good looking out Homie i`ma try that next because this is getting me heated fix one thing and something else go wrong, Replaced the fuel regulator pressure valve and it`s doing the samething it`s getting spark but no fire
