My Dad's 2001 Taurus stumbled and died on him 2 weeks ago today on the freeway. He was able to start it shortly after but it died again a few hundred feet down the road. Power was getting to all accessories and lights but nothing to the starter, not even a click. Had a mechanic look at it where we pushed it to and there was no power to the PCM so no codes or anything. He was able to apply power to the starter and it is apparently working. He called a dead PCM and said they don't work on that. My Dad purchased a new PCM from Autozone that was supposedly programmed to our model etc. but after installing there was no change. Now when we turn the key to start position everything again comes on like normal but no sound at all. Do we need to have the PATS reflashed as well to make this PCM work with the car? Is a dealer the only ones who can handle this? I do hear a faint thump from the rear that I assume would be the fuel pump but that every other fuel pump I have heard makes more noise than that. The theft light also flashes fast and continuously as well which led to the PATS question. I am not sure where to turn next and my Dad is on a fixed income so he can't afford a huge repair bill now at all. I am in the DFW area so if anyone knows of a Ford electronic ace in the area who may be able to give us sound advice?
