I have a 2005 F150 that quit running on Sunday. I checked fuel rail pressure and there was none. Engine turns over but won't start. I checked fuses and they were fine. I disconnected the electrical harness to the VST pump and with voltmeter confirmed that 12-13 volts were being sent when the ingnition switch was turned on, but when plugged back in I don't hear the pump running when the key is turned on. I checked continuity/resistance between the two wires heading into the pump and the meter didn't change so acts like an open circuit. Just to make sure the meter was reading resistance I checked one of the injectors and it read 15ohms which is where it should be.
I've ordered a new pump from the local dealer ($387+tax...ouch) instead of online as I plan to tear things apart Saturday morning and get the pump out and make sure it doesn't work before purchasing the new one. About the only thing I can think of would be if a wire came loose and pump is fine....but I doubt it.
I'm pretty certain the pump bit the dust but would appreciate any other ideas.
Thanks - Dan
