i HAVE A 2002 DODGE RAM CUMMINS 80,000 ON IT IT HAD THE INJECTOR PUMP REPLACED AT 40,000,JUST RECENTLY HAD THE MAP SENSOR REPLACED AND THEY DID THE IN TANK PUMP CONVERSION . ABOUT A WEEK LATER I GOT THE P0216 CODE JUST AFTER INSTALLING THE EDGE ATTITUDE. BUT MY FUEL PRESSURE WAS AT 7PSI AT IDLE AND 0 AT FULL THROTTLE SO I INSTALLED A BD INLINE FUEL PUMP NOW I HAVE 23 PSI AT IDLE AND 17 AT FULL THROTLE IT RUNS GREAT DO THINK I STILL SHOULD HAVE IT LOKED AT. ALSO HAVE CODE P1693 FOR ABOUT THREE MONTHS DEAL SAID IT POPS UP ONCE IN AWHILE NOT TO WORRY. ANY THOUGHTS.THANKS

 

that 216 code is one of the codes of death when it comes to the VP44 injector pump. . .go to a good diesel shop and have the test it out.
