Hi: well, Ford towed my truck to the dealership and replaced the fuel pump, at no cost, lucky my truck is still under warranty, so I got off easy this time. any how thanks for all the advice I learned a lot about my truck --this website is very cool. I still don't have a clue as to the whereabouts of the fuel pump relay, on a 01 F250,
I’ll ask the mechanic tomorrow if I remember.
