Help with 1993 Truck Fuel Pump
Hello I am having problems with my 1993 3.0L Toyota Trucks fuel pump. It recently stopped working the other day. It started out I could Jump the Fp terminal and the B+ terminal and the pump would run and the truck would start. I looked around and worked on some of the wiring and found out I had a bad relay for the fuel pump so i replaced it with a new one. Now the truck wont start at all and i cant even get the fuel pump to work when I jump the Fp and the B+ terminals. I am getting frustrated beyond belief at this point i replaced both of the relays and I dont know what to do. Thank you

Don't guess; use a multimeter. No excuse not to have one http://www.harborfreight.com/7-funct...ter-98025.html Check to see that you have 12v to ground at the B+ terminal (w/key on). If not, suspect the EFI fuse, the IGN fuse, or the EFI Main Relay (in that order).

Thank you guys for your help. I had a couple of things wrong. I had a bad 80 amp fuse. i replaced that and then I used a multimeter on the B+ terminal and I was only getting 6 volts. I jumped my truck and it would run. Turns out i had a bad battery too. I guess when it decided to break down multiple things went. Thank you guys very much for all of your help
