NEED HELP ASAP
 

I came home today in my 1990 ford f-250 with the EFI 460 and it ran like a top pulled hills awesome like normally but when I got home some people on the right side of are driveway so I shut the truck off to see what was going on. It sat for maybe five mins when I got back in it it would turn over so I threw it in neutral and cossted down the drive. I got out checked the relays all the fuses fuel pressuse(witch was Zero). ANyone had this problem happen to them and I have all power to my fuel selector but my fuel pump dosn't sound like it kicks in like normally and I have no power to my rear tanks is there a switch or a fuse that goes to there? I really need help fella's
