I adjusted the lift pump tdc timing from -1.9 to - 0.1 . Everything seems ok now. Just need to clear history codes and I should be good. Thank you for info.
Any ideas? I have a 2000 k2500 with a 6.5 turbo diesel. 245km on it. Runs a bit rough. Starts good. Has an erratic throttle and thick black smoke on acceleration. Can't hold steady throttle. Swapped out pmd module with a known good one. Repaired numerous grounds that were bad or missing. Any...
