Had a load of bad fuel.. cleaned everything in the fuel system out. Engine died on water. Mechanic replaced vst pump and filter..got boat back and it still ran like crap and stalled out..Decided to dive in on my own and learn this engine and pulled everything apart.. cleaned injectors and pulled hp pump apart.. 1 filter was loaded with crystalized crap. Replaced filters/screens and started it up on separated tank of fresh fuel. Ran yds diagnostic software and got and Atmospheric pressure sensor .. code 22 error. Cant for the life of me seem to find out about that on where it is!!! Is it labeled with another name? Map?? Engine does start right up and run but it get surging and will still stall out unless run at higher rpms..changed both LP pumps also..Anyone have an idea?? TYIA
