I have a 2003 Jaguar S-Type R that is currently in a restricted performance mode.I have a check engine light P1339
I have rough running on start up, and it will not go over 3k RPM.
I looked this up and found that P1339 is
Fuel Pump Driver Module Communication Circuit (Fuel Pump Driver Module). Is this just the circuit or the module itself? How can I test the module with a meter? Also, is it a programmed device? Can I just swap it out or do I need to have it programmed?
