I purchased a Zetec from the junkyard with the list of misc parts. I have to reprogram the ECU because the Passlock from the car has 4 plugs and the computer and Passlock I grabbed with keys only has 2. I don't know if the motor runs or not so I have tried to jump the starter just to see if it turns over well but the starter does not grab the flywheel. I have tried the original starter for the SOHC as well as the one from the motor I pulled. Any thoughts why the starter does not turn the motor over? Do I have to have the ECU programed first? Any thoughts or advice would be great!
