I recently had trouble starting my truck when it was warm. It would always eventually start but I had to pump the accelerator a few times or it would stall. The fuel pump was also noisy when I turned the key to the run position so I first thought it was the fuel pump for sure.
After reading the comments on this site I noticed similar complaints with the fuel pressure regulator so I thought I would try that first. Worked great! The truck starts perfectly and the fuel pump is not noisy anymore.
my truck was difficult to start when warm and sometimes stalled when slowing to a stop in idle. the dealer cleaned the throttle body which did not fix the problem. they next wanted to replace the fuel pump (~$900). after researching on line, i replaced the fuel pressure regulator for about $50 and the truck starts perfectly.
I had problems with the truck not wanting to start within about five to ten minutes after I had shut it off. I figured that with it's mileage it was probably the fuel pump, so I replaced it along with the wiring harness seeing as Chevy went from a square for wire hook up to a rectangular four wire hook-up. Still had the same problem three hundred dollars later. At this point there were so many things it could be I took it to a mechanic. They replaced the fuel pressure regulator and it's worked fine since then.
