will fuel pump work with bad ECU
the tittle says it all. i was trying to see if my fuel pump works because im the process of building my fc and was checking to see if i can get the pump to kick in. i turn the key to on. or crank the car and the pump still doesnt turn on, im not getting volts to the pump but i am to the fuel pump relay but its not turning on, anybody have any idea's?

The pump will pump with a bad ECU.
Do you have V coming out of the relay? Have you rewired your relay yet? The pump only pumps during cranking then the AFM takes over after start.

The pump should have run with the key to START.
If the pump won't run with the fuel pump check connector jumpered, but you get voltage to the fuel pump relay and resistors Blue/Red wires.......then ohm out the Blue wires at the Fuel Pump Relay and Resistor back to the fuel pumps connector (the single Blue wire).
Your ENGINE fuse good????

the fuses are good. i dont have an engine harness, i dont have everything plugged into my engine harness but i dont think that would matter because i know my old TII S5 pump turned on with the harness not plugged to the engine, i also havnt rewired the pump yet either. should i?
