Im starting to feel like a B*tch and its killing me

 

Sounds like quite a project , am a dodge drivability tech by trade. So I will see if I can help. If you can get a pressure reading that would be a good first step.Also are you running a return line to tank . Check to see if pump is getting hot and check wires to pump , for getting hot . ALso are you straight wiring pump or running thru a relay. Check this out first hope it helps. You can email me if you like at keswanson61@netzero.com Good luck erik

 

thanks for the help, but I finally found the problem....after 6 weeks of frustration.....It was a clogged gas tank vent..... Man I thought of everything else but the simple. hehe
Man I went from testing every sensor, to my wiring , to replacing fuel pumps relays and alll... to stumbling upon this problem...
