Ok so I took a wire put it from the battery to the B+ Engine light on then took another wire from the FP to B+ got fuel have spark as well. What I will probably end up doing is just have a wire go from the battery to a toggle and then run another wire to the B+ and fuel pump. There's some vacuum leaks I need to address she's almost starting though. We shall see......

I'm glad your rig didn't catch fire. (Yet.) A car battery can easily deliver over 100amps; connecting it directly to a circuit you are unfamiliar with can sometimes lead to a spectacular result.

Connecting FP to B+ is for diagnosis, not driving around. Your truck is built so that if you get in an accident that breaks a fuel line, the fuel pump will stop. With FP connected to B+ you don't have that protection.

While you're looking for those vacuum leaks, I would advise you continue to look for your electrical problem. Since you have already checked for voltage on the EFI Relay socket, and confirmed that the relay is good, you only have less than 6cm of wire to now check to find your problem.

Good Luck!
