I got a problem need some help with my father in law just bought a 87 f150 4x4 with the efi 302 he was out test driving it and someone didn't tighten the battery terminal and while driving the terminal came off the battery and killed the truck. after figuring out what had happened and replaced the terminal on the battery the truck wont fire. It has spark and turns over just fine but wont fire like it has no gas going to the efi any ideas where to look we have looked at all the most obvious in the dark and cold may have over looked something. can anyone help?
