Read a bunch of threads on the topic but still confused. 1997 K2500 Vortex 5.7L.
Symptoms: hard starts - have to crank for many seconds to minutes if it even starts at all, engine stalls and misfires and dies if running, bogs down under throttle. It is a relatively new issue.
The fuel pump sounded weird and I thought the check valve might have failed so I changed it and that didn't fix it. I have 55-60psi at the fuel port on the intake but it bleeds off to 20-30psi in less than 10 minutes. This isn't normal is it? I think this means that my fuel pressure regulator is leaking and I probably need to replace it and the spider. I want to be sure though since it is expensive.
Any other things to test? My distributor, wires, and plugs were changed less than 3000 miles ago. Any other sensors failing that would randomly cause this?
Thanks for the help.
