When I changed the Crankshaft sensor the air conditioner compressor had rubbed one of the wires into I fixed it and put a new crankshaft sensor again. Checked all the fuses all we're good shape. Checked the fuel reset switch it was in good shape. Still not getting fire to coils

If the crank shift sencor shorted out would that short out the PCM computer?

Sorry with the key on the theft light goes out
Ford Mechanic: AMEDEE, FORD TECHNICIAN replied 2 years ago
Thank you for that information.
What about the check engine light?
Does it go on with the key on and go off while cranking the engine over?

No it Does not come on
Ford Mechanic: AMEDEE, FORD TECHNICIAN replied 2 years ago
Ok, the check engine light should come on with the key on. IT is turned on by the PCM. It sounds to me like the PCM is not awake with the key on. I would recommend to check all powers and grounds going into the PCM with the key on. This includes all powers from all fuses and the ignition switch. Chances are the PCM is not getting powered up.
If all powers and ground check out good, then we need to check to see if one of the sensors that receive a 5 volt reference with the key on is shorted out. Based on my experience, the crank sensor cannot short out the PCM because it does not receive a reference voltage with the key on or when cranking.
If all checks out good, I would suspect a bad PCM.

When I turn the key on the check Engine light comes on. But when I crank it the check engine light goes out
Ford Mechanic: AMEDEE, FORD TECHNICIAN replied 2 years ago
Ok, good, check to see if the ignition coils are getting power with the key on and while cranking. If so, then check the ground signal trigger from the PCM to the ignition coils. If the PCM is not triggering the coils while cranking, the PCM is bad and will need to be replaced.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
