1995 AWD talon...
when i turn the key on the pump does not click on for that split second and when i try to start the car same problem, no pump...
i followed the power wire all the way to the mfi/fuel pump relay relay and if i give the pump power using another battery and ground the pump goes on, so i know the power wire going through the cars frame is fine...now i tested the harness on the MFI relay and when i turn the ignition on, the black/white wire gets 12v's but the fuel pump power wire (black with blue line) does not
i then spliced into the fuel pump ground wire on that harness (white w/pink line) and i grounded it to the car then turned on the key...the pump went on and stayed on until i broke the ground connection...
so this iw where i stand...the ECU is not sending the "ground" signal to the fuel pump relay..does anyone know where i can view a schematic of the ECU? that way i can see which wires are meant for ground on the ECU and i can then test those......any other suggestions would be appreciated, i hope i made sense
