fuel pump issue?
My 2000 1500 started to miss at different speeds and then sometimes will not start.
My mechanic said most likely a fuel pump. I thought that maybe I would try to eliminate one issue and replace the fuel filter, but when I loosened it, gas ran everywhere and would not stop. I got more than 2 cups before I gave up and re-tightened the old filter. My question is does that indicate a blown pump if the gas keeps siphoning through the pump? Thanks for any help |

the fuel filter needs replacing 30-40,ooomi have a small cup to catch the fuel ..you could also use a small funnel with a hose to it and direct the fuel into a container.. what is needed is to check the pressure with a pressure guage..you need 53-62 psi with the key on to start..then the pressure with key off should hold with in a few psi after 15min.. a new pump should put out 60-62 plus psi with key on engine off! use the purolator gas filter good quaility at a fair price. if the pressure is low get the delphi pump//no airtex pumps ! |

Re: fuel pump issue?
Thanks for replying,
I heard I would get a small amount of gas from the lines but when I disconnect the filter the gas POURS out. I funneled about a cup into a gas can and used 3 bath towels soaking up more.... still didn't stop. I thought maybe there was a part of the pump cycle that would let it do this. So I primed it and repeated the procedure ( pulled relay,relieved pressure, pulled filter) same result. Thanks again |

Re: fuel pump issue?
When I checked the pressure it primed up to 60 then ran at 50 -55
When it was missing and then stalled it dropped to 40.. Sometimes it was at 0 but also would not start, guess its a pump or wiring issue Could this be a pressure regulator problem? Last edited by petedownload; 06-07-2011 at 06:24 AM. Reason: added sentence |

since the pressure is varying greatly this looks like a pump issue.. also if the pump is replaced the fuel filter needs replacing. the ground at the frame rail fuel tank may also be corroded to copper dust.. |
