Fuel pump ground? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

harness in RH fender well was rubbed open and wires frayed.

also, had same problem in my 20v corolla with different solution. in the corolla, the voltage drop through the wiring was too large. Fuel pump only getting 11.x volts from COR. I checked 16v wiring diagram and the COR actually got 12+ volts from two wires. ran the extra wire and it runs like a champ.

surprised to see this thread back after so many years.

eventually i swapped an ls1 into the 240. made a pnp harness with e8, e9, and f1 plugs. no issues afterwards

dreamin240 - check the diagrams to verify where the ground is. then check the ground. i think it is on the taillight valance or quarter panel somewhere
