Hey. Thanks for the reply. Your comments seem to be directed at fuel issues.
I am trying to remember details of discussion with the mechanic a few weeks ago, but I believe he said the fuel pressure was about 65 psi at startup, and at some point dropped to 52 psi, then back up to over 60 when running. I hope this makes sense. We had no discussion at all about fuel pressure when return line pinched, or after engine was stopped. I will get this all re-checked!. As well as voltage drop test at fuel pump.
I have a new fuel filter on the front seat of my truck (no good there, I know.) So I will try to get this on myself in the next day or two.
At what point might you think that the problem could be injectors leaking or sticking? I know these 96-03 Vortec engines have problematic poppet valves in the injector nozzle? I am bracing myself for this possible diagnosis>
And thanks again. I really appreciate this feedback
