Set the engine to the number one compression,and bring the timing mark to zero on the harmonic balancer.(or just bring the timing on the harmonic to zero). mark to match the plug wires to cap,remove the cap.(if you can remove the cap without removing plug wire) mark the rotor position to the engine using a scribe, mark the rotor to the distributor, mark the distributor to the engine using a scribe,Take the lock down bolt out and pull out distributor. when you reinstall line up all your marking and check timing.

SOURCE: ignition control module location for 1997 ford thunderbird?

It should be right on the side of the distributor, a small ( usually grey ) plastic type box with 4 connections on one end if i remember right.

Check you coolant temp sensor ,If it is bad it will be reading{ 40 degrees below zero }and this will cause a rich condition due to the computer thinking it is that could outside, which requires more fuel .:)

SOURCE: ignition alarm will not stop 97 ford f150

To get the chime to stop you need to take the ignition column cover off and the ignition switch out. Then you need to check the little wire and clip that is still attached to where the ignition came out. If it is still there it needs to be fastened back in place. once done chime should be gone!

Did you also change the Coolant Temperature Sensor? If it is reading wrong, the computer may not realize the engine is cold, and won't increase the gas for that.
Spray some carb cleaner around the outside of the throttle shaft, if engine speed increases, that could be a vacuum leak. I've never heard of that, but anything is possible. It sounds like it would have to be a serious air or vacuum leak to cause your problem. Have you blocked off the power brake booster to check if that is leaking?

You might want to do a compression test to see if there is any internal mechanical damage.

How do you replace a ignition modulel on a 1977 ford f150 m in the distributer

On the 1977 the ignition module is an aluminum box that should be mounted somewhere in the engine compartment. The ignition pick-up is mounted inside the distributor and you must remove the drive gear from the shaft in order to pull the shaft out and slide the pick-up off the hub of the distributor. This is not an easy job and most people try replacing the module first as it is usually the problem.

1991 F150 quit running

You need a new distributor. You've replaced everything else. A distributor will get up and running again.
