Fuel Pressure Problems...Won't start I have a 01 5.3 in my 71 monte. This what I have for a fuel system.
1994 Roadmaster tank w/Walbro pump
Stock 2001 5.3 with fuel regulator / return
When I check tghe voltage going to the pump with the key turned on, I only get around 6 - 8 volts then it goes to 0. I can hear the pump priming and that's it. When I check for pressure theres nothing. I open the schrader valve and get a little air and fuel spray then it goes to nothing.
I also replaced the fuel pump relay ( no difference ). Should I be checking for leaking lines, FPR problems orground issues?
