Check for a short, or partially broken wire between CDI and coil. If your wiring is goodbetween there, check between CDI and pick up.

I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Hi.

The PCM is located in the rear right corner of the engine compartment, sticking to the firewall:


The PCM can be replaced with a new or used god-working one. In both cases the PCM must be reprogrammed using a Tech 2 tool that costs about $3000. The operation is done at the garage.

The PCM is unlikely causing misfire on a single cylinder. Check wires going to spark plugs. If the coil is getting no 12V on the ignition side check ignition. It is strange that one coil has no power, the engine usually does not start when that happens because the same coil gives power to spark plugs on different cylinders.

Check if there is a capacitor fixed to the head aside the coil (there should be one). It should be cylindrical and one inch long, held by a single screw and located aside the coil. If there is a capacitor, that must be replaced with the coil. If you have not replaced the capacitor that is probably involved in the problem.

If you have already replaced crankshaft position sensor, check crankshaft position sensor harness in PCM. I uploaded here the bulletin with CKPS to PCM testing:2003 Taurus CKPK PCM testing.

Test the PCM and CKPS connectors. Check again voltage to coils and spark plug cables. I understood that spark plug cable nr.3 has no spark from coil. Check DC in from ignition to coil.
