Hello, Mr. Amedee, My name is***** I have a P73 Crown Victoria car, (retail model, civilian model) which has been running like a top for years, we have had it since new, it is a 1999 model, 4R70W transmission
350K miles. No major work ever on the car. The car has been well maintained and Ford does not make the car anymore, I know I could obtain a 2010, or 2011 model but it would be a LX model which has even more electronics to maintain. The problem I have is that the car recently started not wanting to start, although the starter
turns, as if you are using the wrong key, (we use non-pats keys to open the doors, and trunk) it acts as if the door key is in the ignition, instead of the PATS key. So, I took this to be a PATS problem (PATS type "B" 1998-2002 Crown Victoria). I hate the PATS system -- it is always locking me out of the car when the car is running. The other day the car was driven 30 miles, parked for 2hrs. then it would not start. I have 3 PATS keys in the car, tried all three, none would start the car. I un-hooked the battery, waited 15 mins. and tried again, still no start with the first PATS key, tried the 2nd key, then it started. I just left the car running while I went to the grocery store, and it was still running when I came back (30 mins) there is no hesitation, or skipping once you get it cranked, so I do not think it is a fuel issue, but I am not an expert with electronics. In any event, and to try and make this rather long story shorter, here is what I did to try and fix this problem: I went to a junkyard and pulled a p71 (cop car) PCM module off of a 1999 "interceptor" car. I did this because 1999 cop cars do not have PATS, and I do not want a PATS system. I installed the cop car PCM without any programming, but the cop car PCM will not start the civilian car. So I put the original PCM back in and now the car will not start with either PCM. The PATS light flashes on and off quickly and you can hear the fuel pump going on and off quickly inside the gas tank, where normally it will come on only one time -- the sound is the same, it just cycles now. The PATS module is still hooked up. The starter relay on factory police cars was always grounded, and this is how a police car starts without PATS. But I do not know how to wire a starter relay to ground, at most, I would class myself as a "C" grade mechanic. I do know where the starter relay
is, because I pulled it off and the car stopped cranking. I am not trying to make a police car out of an old civilian car. I just do not want to be bothered with PATS anymore. Can you tell me what to do? I do have the VIN # ***** the donor police car, and the PCM is marked: XW7F-12A60-CB which is one of the ones supplied for 1999 police cars, (ARA1), MlC-411. I even opened the covers on the police car PCM, looking for water damage, insect nests, or markers of heat damage on the circuit board -- nothing the board looks brand new -- also none of the connector pins are bent -- I looked real close. I am not even trying to save money -- I just want the PATS system off the car. Since the car is not running anyway, could I send you the police car PCM and perhaps you could program the thing to work in the civilian car? I will pay standard repair fees and shipping for all services. Thanks.
