Technican: To replace the ignition lock cylinder you'll need to remove the steering wheel and unfasten the turn signal switch to pull it up and reveal the lock screw that retains the ignition lock. Is this an air bag car? Are you prepared to disarm the system? Does the ignition key unlock the car doors also? If you replace the ignition lock cylinder and don't have it recoded you'll have an extra key to deal with from now on. If adding a new key to the mix is not a problem we'll press on. If it is undesireable we'll need the help of a lock smith.

Owner: unfortunatly that incorrect. I got tired of waiting and figured it out on my own, there is a pin on the under side of the steering wheel that allows the barrel to be pulled with the key in. although the key was broke that is apparently not the only problem as the car now only "dings" with the key installed. when turned on, the volt meter goes to zero and nothing happens. we have checked the battery and it is fine I believe the problem might be the ECU ( fuses maybe?). when checked from positive post to the car body it shows 13.4V as well as from pos. to neg. post. Anythoughts?

Technican: You got tired of waiting on what sir? This thread shows I waited four days for your first reply. The ignition lock cylinder doesn't seem to actuate the ignition electrical switch properly. Does the rotation feel right but the results are not correct? I just did a T-Bird that I found the electrical ignition switch had literally seperated from its metal case enough that the switch contacts were gapped open so that no circuit could complete. Have you inspected you ignition electrical switch? Is battery voltage present as an input but cannot be output when the lock cylinder is rotated? Do you need wiring color codes for ignition leads? I'm not ready to fault the computer.

Owner: yes. rotation seem correct now. when my son told me of his problem the key went all the way around, so I obviously wanted to replace it. While i was under the column I also replaced the ignition switch, it was fairly cheap. the auto seems to have no power at all yet all the readings i've taken so far show voltage where I thought it should be. I'm stumped and so is my brother in law who is a ford engine engineer.

Technican: Do you have wiring schematics with color codes for the ignition wires? I'll email or fax one to you if you'll tell me where to?

Technican: Have you checked the engine compartment fuse box IGN SW fuses? There are three of them each rated at 40 amps. They supply the power via Yellow wires to the ignition switch and the starter relay. The starter relay is also in this fuse box.

Owner: are theses fuses in the ECU box? I checked all those and they seem to be fine. there are two relays that have not been tested

Technican: The fuses I'm referring to are in the power distribution box under the hood on the left fender apron forward of the shock tower. These are the fuses that take the place of fusible links. How many yellow wires show to be supplying power at the ignition switch connector? There should be three. Do you want me to email or fax wiring diagrams? Where to?
