Question

Need help with my 91 ford f250 fuel pump etc. ?
My 91 ford f250 , 351w automatic, 2wd. Today when I drove my truck and then parked it for 30 minutes, I went back to start it , it ran rough for 2-3 seconds twice and then I had to use starter fluid to fire it up. I'm getting fire to the coil but it seems like I'm not getting fuel.The relay in the drivers side seems to click when I turn the key but I don't hear the fuel pumps run.The fuel selector switch is hard to switch.Is there anything else that I can check or test? I heard there's three pumps, not sure if mine has three but does the third one affect the intank pumps?

Additional Details


is there anything i can do to diagnos, so i know exactly what is wrong?

Answer 1

Maybe someone bumped you truck & the fuel safety switch was triggered. It's located behind the passenger side kick panel.
