 1987 mustang ignition wiring
does all the wiring on the ignition suspose to have power. Im having problems starting my car and i think it has something to do with the ignition. all my wires on the ignition have power when the key is in on position except the white with pink wire in the diagram it shows that it goes to my starter and TFI module. when i turn the key more to crank it starts the car but when i let it go the car shuts off. I traced the wire it goes to a harness when i disconect it from the harness it has 4 volts and when I plug it back it shows no volts and it gets grounded. Do I have a short? Can someone help me out with this. |
