running issues 2000 yukon denali
i have a 2000 yukon denali that stalled on my wife in the drive way , i tried to start and it would not. i tried starter fluid and got it to start and run. but after a few minutes it begans to run rough and stall or when i turn the wheels. i have replaced , plugs, wires, cap ,rotor, fuel filter, checked fuel pump it is working and has good pressure. alternator and starter new. when i changed cap and rotor , distributor was loose i chacked timing with light and tightened . security system is disengaged. im running out of ideas.
thanks
also after i get it running and it stalls it is hard to resatart and runs very rough

its a vortec 350 right? what was the pressure exactly they are real sensitive to having the right pressure. there should be over 60 key on engine off and it should stay for a while. and it shouldnt go down that much when running. also was the the dist loose enough that the timing might have changed?

i believe thats too low. theres a few things that can cause a drop, you already did the filter. a leak, fuel pressure reg could be bad. or your pump could be going out. you could also have corrosion starting in the pump connector but its a pain to get to so if you drop the tank you might as well replace the pump/ sending unit
