Ok 97 Chevy s-10 blazer. You must prime throttle body to start it. After that runs like a champ.Fuel pump elec in tank was replaced in 09. It did not come with retro fit harness. Gas gauge quit 3 months after new pump,but it ran fine.
Replaced regulator. Replaced IAT sensor,next coolant sensor. It carries 55lbs fuel pressure which manual shows is in good range. Yes I replaced fuel filter. Yes I have hit key three times to pressurize system,still have to prime it!
AAHHGGG HELP! anybody run up on this one before?

Intermittent short in the fuel pump wiring harness. Had this happen in 91 Chev pickup and 94 Caprice. Put 2 fuel pumps in the Caprice and replaced the fuel pump relay before I figured it out. In the 91 Chev, the symptoms were exactly what you describe.
ReplyDeleteNairb,thanks Bro!When I replaced it seems I must of bought the last remaining fuel pump in the country that had original old style harness.The replacements have eliminated the defect!I was afraid of that! Oh well another Sat and about 3 bills.
