Need a PCM for 2004 lightning .Truck has been sitting at a Ford dealer for two months and they can't fix it.Truck won't start unless you leave the ignition on for 15 minutes with the key in the ignition everything's been replaced in the PAT system. Dealer said I need a new computer can't seem to find one and neither can the dealer if anyone knows how to delete a PAT system let me know but I hear that that's impossible-I live in the Tampa Bay area of Florida
