[QUOTE="BLU3VN0M, post: 15381579, member: 130270"] it's not a PATS issue, its a wiring issue.. i've gone through this a few times now. 1) check grounds. (motor mount to chassis, battery to chassis, 2 harness grounds near the headlights, PCM ground in the passenger footwell, FPDM ground in the trunk) 2) What is done to your car? Fuel pumps? BAP? WOT box? etc.. all those have connections which if loose, will cause the PCM to produce dashes. Check all the wiring to any mods done to your car and make sure the connections are good. 3) If none of those fix it start pulling your connectors on the engine bay harness and checking for corrosion, bent pins, loose connections, etc. Make sure the C133 connector is tight (large connector with 10mm bolt on top near the firewall on passenger side). Also check the 10mm bolt on the PCM connector to make sure it is tight and no bent pins. I just tracked down a major wiring issue with mine. It's a lot of headaches, but you'll eventually find it. If none of the above works you're going to have to resort to a multimeter and the Ford manual to check the resistance in each individual wire to the PCM to track down where the short is. Good luck!
