I recently have started having a lot of problems with my 2002 F150 computer and associated equipment. My truck stalled while driving. It would not restart. When I tried to restart it, the instrument gauges went crazy and the theft system prevented it from starting. I have had the PCM and the instrument cluster replaced. The mileage was reading all dashes and the PCM would not communicate with the PATS. Since they communicate through the instrument cluster, this indicated a bad cluster. They changed both parts, reprogrammed, and everything worked. I was 3 miles from the repair shop and ran into a store to buy something. I started to pull out of the parking lot and it dies again. I got the dashes and the theft light blinking again, but the gauges were normal. It is in the shop again. I just wanted to know if this problem has occurred with anyone else, and what could possible keep taking out the computer like this. Any suggestions?

 

I did not receive any suggestions or replies, but in the meantime the problem has been resolved. They found that there was a fuel sensor circuit from the gas tank to the computer that was faulty. They replaced the wiring and the fuel sensoe and it appears to be working good. Hard to believe that this was frying the computers and also the instrument cluster.

 

Thanks for the update..
