I have a 2007 GT and have experienced the following problem last summer/early fall when the weather was still hot. I drive the car home from work, about a 50 minute drive and the outdoor temps were pretty hot, about 91 degrees. I get home, shut the car off and go in the house. Come out 5 minutes later and the car won't start, not even a click. My battery is recent and has full charge, lights and stereo work etc. when this happens, I notice the anti-theft light flashing on the dash when I put the key in the on position. I have tried multiple times to repeatedly unlock the car, lock, unlock etc and makes no difference. I tried my spare key, fiddled with the key, banged a little on the steering column thinking possible loose connection to no avail. I read some posts about the module in the steering column going bad and unable to recognize the keys. The thing is, both times this happened, I let the car sit for about an hour and tried again and started right up. I decided to have the local Ford dealer diagnose the problem. They were able to reproduce the issue after running the car for about an hour, seems to be induced by temp. They said the PCM is overheating due to a faulty circuit in the PCM. They quoted me $1200 for the replacement of the PCM, part was about $750, the rest is labor to replace and diagnostics. Freaking sucks since the car has only 34k miles on it, but I have no choice as I can't drive a car with that kind of reliability problem. Anyone else experience a problem like this with the PCM? I am running a Steeda cold air kit and BAMA tunes, using the 93 Race tune. Wondering if the tune could be adding to/creating the problem? I ran the same tune the prior couple of years without issue, but I do notice the fan runs quite a lot with this tune compared to stock (expected but comes on very soon after startup before engine is warmed). Appreciate any input and thoughts from the group before I throw a good chunk of change to replace a very low mileage PCM with a refurb that likely has many more miles.
