Driving home and the car dies (1990 5.0). Figured out the fuel pump was not running so changed out the pump in the tank. Did not work. still not running. Now I figure its in the wiring. Checked out the relay under the driver's seat and it still clicks when the key is turned on. Power to the green wire to the relay constant. Little red wire only when the key is on. Yellow wire makes relay click and pink/black wire has nothing. This is the wire which goes to the back. tried a jumper wire to puit power to it and still nothing. Any thoughts on the situation or things to try? I am at a loss here .
