gearbox 10/6/2012what kind of scan tool showing coil pack bad? check the wires at the coil pack for a loose pin. easiest way is to unfold a paper clip shove it in to each pin and see if it falls out if shaken (I'd go with a everyday size one.. sorry don't know the size as I steal them from the shop cashier)
Also since you have basically gone for broke, next I'd recommend a dealer to insure what is missing as those with an IDS (ford dealer scan tool) get a few more things to help diagnose with. as If I remember ford stop using the plastic gears in the 1990s as I personally haven't had to do a chain job on one yet and I see a few 200k mile plus vehicles using this motor.
give more info on what you are seeing exactly
car doctor 10/7/2012Gearbox, I am also getting a full 12.6 volts at the module with the ign. on. May have to take the new PCM back to ford and have them re-map it again......don't want to have to take the whole truck to them because I will have to pay an outragious towing bill also if the timing chain was off a little bit, I don't believe I would have such good compression on ALL cylinders and the manifold vaccum is at 16 inches. May just have to "bite the bullet" and take it to the dealership and fork over another grand.
gearbox 10/20/2012Not always as the cam position sensor if it was installed 180 degrees out can cause the codes you are reporting (Ford had a tsb out on this issue, but references using a ford scan tool to diagnose proper placement) Unless I can't get from Ford, I don't do aftermarket as the rebuilders are many times good, I've seen some bum ones but with codes you are getting, this isn't the case IMO.
Wish I could do pm to diag lot easier as I said haven't had time to help you in real time as I should.
HouseCallAuto 10/20/2012I want you to detail what the car was doing when you first went to work on it? Why was the vehicle brought in to you? I assume it is not your own car, but a client?And if it is your vehicle, what was the fisrt symptom? Did anything you did so far do much of anything or is it for the most part unchanged in the way it is running? also, can you state the code numbers please and not the titles?
