2007 ford fusion 2.3 engine automatic transmission no crank.
I did an engine swap. Car cranked up a few times then all a sudden it wouldn't crank back up. All dash lights comes on anti theft light comes on and goes out when I turn the key into the start position. If I jump the S wire to the battery wire the car starts up. I swap the ignition switch from a used car still nothing. And the starter relay is none serviceable in the smart junction box driver side kick panel. Any idea to what I should do? I try to repair my own cars but I'm will to pay for a live video walk through of me diagnosing it if possible. Thanks for reading this.
