i recently had a blow out on my 90 Ford PU and changed the left front tire. I tried to start the engine, but it wouldn't start, i towed it home. it had gas, I checked that. I had a friend come over and we started troubleshooting. There was fire. I looked in the owner's manual, reset the inertia switch, but the fuel pump would not kick in. I replaced the fuel pump, but it still is not kicking in. i had the inertia switch tested by a mechanic and he said it was good. it does make a rattling sound, is this normal? I'm thinking or replacing it anyway as well as the fuel pump relay. any suggestions. The truck never had issues until the blow out. Definitely i'm not getting power to the fuel pump. i appreciate any advice before i tow it to a shop.
