I had a thread a few weeks ago. i replaced the pump on this truck- the first one was a bad pump-sent it back and the second one worked great. he reinstalled his blue chip fms (runs it about 33%). it has been FOUR WEEKS since i put this pump on. it has a fass 150 filters are new. today he called me saying it had a dead pedal- my scan tool pulled p1693 and p0216. started and ran it for a while- it idled rough but would rev pretty smooth. after i killed it i checked it again and 0216 and 1693. WHY ARE THESE PUMPS DYING?? i don't understand
