I have a 95 240sx se that we pulled the ka to build with forged internals, head work, turbo, top feed fuel rail, etc...
Fuel pump was working for a few hours when we were trying to finish up the new top mount fuel rail and all the little stuff after we dropped the motor in.
But now I have power at the fuse but no power at the fuel pump relay which is like a foot away. Needless to say i have no power at the fuel pump so it doesn't prime or run. I have taken the fuel pump out of the tank and it works fine when hooked up to 12v.
I have triple checked all the grounds in the engine bay. The fuel pump relay has a good ground to it, also checked to see if the other 3 wires were getting grounded but they weren't. I have replaced the relay's for the fuel pump and egi relay. I have checked my ecu in another 240 and the ecu works fine.
So unless i am wrong there is something between the fuel pump fuse and the fuel pump relay that is not allowing power to get to the relay. It couldn't be more than a foot of wire.
I am not sure what to do next... Any help would be greatly appreciated
