my father had a brilliant idea to put a fuel cell and a inline fuel pump on the truck. 92 dakato with a 5.2. problem is pump works flows fuel but he has lost injector pulse. my guess is it has something to do with the main electrical harness to original tank being disconnected.
if this is correct can someone tell me which wire needs a signal to engage the injectors? or show me a wiring diagram so i can finish his truck for race season. all replys appreciated

 

Injectors have a constant positive signal, think is orange and each injector fires from a negatice signal from the computer. I believe the fuel pump wiring is pos neg for the pump, pos neg for the leveler and a low gas pos, for the low gas light trigger. Sounds like daddy messed with something under the hood.
