What Kind of screws are holding the ICM to teh distributor on the 2.9 ? Phillips torx etc?

 

Not for sure how far back but we used the little ignition wrench i think it was a 5.5mm. They still see them at most parts stores if that is what you have.

 

They are hex head for sure, not Torkx nor Phillips head. The 'socket' body has a very thin sidewall to be able to slip into the hole in the TFI. The "Help" section as some parts stores carry the wrench, with a built-in **** style handle. If you do replace the TFI, make sure to use the heat sink compound, and be careful when you remove and install to move the TFI vertically from the bowl of the distributor. There are connections on the top of the TFI that poke up into a connector on the bottom of the bowl, and the connections can get real wobbly if the internal pickup has gotten rubbery due to age or oil or heat... You CAN get the connectors to work without replacing the internal pickup if you are very careful.

The wrench is an alan wrench right?

 

No its like a **** with a thin wall hex head. Go to your parts store and ask them for a Ford Ignition Module Wrench. It should cost around 5 or 6 bucks.

 

This wrench doesn't require you to move the distributor:


I'm waiting to get mine from Amazon to do this same job. I tried using an OEM ignition module wrench, and it would require me to rotate the distributor, which I prefer not to do.

 

I use a 7/32's that I have turned down to fit in the hole. And yes they make a tool to for this job

 

I tried using the CTA tool. It easily got the front screw out without moving the distributor. However, I had to rotate the distributor to reach the rear screw. While the tool reached it, there was not enough room between the distributor and the coolant temp sensor housing to make it work. The PO had already marked the distributor position.

The OEM tool is less expensive, and would have worked just as well.
