fuel pump problem???
I have the stock 3.0 fuel pump still in my truck with the 5.0 just last week it started to stall when idleing. I can keep it runing if i stay on the gas so today i did a fuel presure test and its at 50 psi when runing then when it starts runing ruff the presure starts to drop. it stalls when it gets to 20 psi then goes to 0 and wont restart. guage stays on 0 have to cycle the key 10-15 times then you can hear the pump go from high pitch buzz to the normal pumping sound when it does that presure goes back to 50 and will run for a little wile then do it all over agen.is the pump bad or is it something elce? i dont understand how if the pumps bad i can fether the gas and keep it runing i mean i could drive it all day on highway but if i was in stop and go traffic theres no way. any ideas? this isent my daily diver anymore so maby upgrade pump well im at it?
