im rebuilding my whole car. im am redoing the whole wiring. i have my turn signals, lights,rad fan,front wiper on switches. I am going to be putting my fuel pump on a toggle switch to. Can i do that and get rid of the main relay? Just need a ground and power for fuel pump to turn on right? I wont need the main relay? thanks..

 

 

The PGM -FI Main Relay is two relays in one, one supplies power to the fuel pump, controlled by the ECU, [supplies a ground to relay coil] the other relay is the injector relay, it supplies power to the injectors, ECU and a few engine sensors, it is controled by the ign. switch, [supplies 12V+ to relays coil] so, no you can not get rid of the main relay, unless you do a lot of rewiring. 94

 

do you know a link? i am re wiring everything i can. less wires in back neater look. this car is 100% stripped. Is there way can leave the main relay for the injectors and just have the fuel pump on a toggle switch to manual turn on?

 

ill keep the main relay. i just wondering if i can cut the wires to the fuel pump and leave the main relay and then wire my new fuel to a toggle?

 

You would eliminate one lead, [ECU control lead] only to replace it with another, a fused 12V+ to a toggle switch, [and the switch].

I don't see the point, as it does not eliminate any wiring. 94

 

this sounds like what im doing. i got rid of all factory wiring, and took apart the engine harness and used only what i needed.

i also picked up a painless type kit for the rest of the car so no more main relay for me, just switches.
