I have a 2001 Cummins 4x4 6 speed manual. With edge comp box. Valair DD Clutch. It has a small lift pump on the frame rail. The filter is an external unit from the LP. Also the previous owner said that it had an Industrial Injection Hot Rod VP44 Injection Pump. It is Otherwise stock. Today when I got into the truck to drive to work it had the Check Engine Light on. So I cycled the key three times and read the codes. They are PCU - P0163 P Done P ECU - P0237 P0382 P0380. I have noticed that when I get into 5th and 6th gear. If I’m not heavy on the pedal that it likes to shutter a little. Like fuel filter is clogged or if your in to high of a gear going up an incline. It’s not a bad shutter. But an annoying one at that. So I was planning on doing. Valve lash. Fuel filter with seam foam or Howe’s meaner cleaner and an oil change with oil stabilizer. I also plan on installing my FASS Titanium 165 with 1/2 lines and Sump when I get the time too. Does anyone have any suggestions. . I’d love to verify what these codes are and what I need to do. And if I should be worrying about them. They are getting fixed regardless. But idk what I should expect price wise for parts. Also got code P1689 no communication toinjection pump from ECM. Still runs good. I have read that crank sensor and or map sensor or fuel filter have solved this code. Anyone ? I’m doing fuel filter crank sensor and map sensor today along with an oil change. This is my daily driver / work truck. I depend on this truck to make my money so it has to be 110%. Any help would be wonderful
