Trent, welcome to the TDR; you have come to the right place in addressing issues with the 2nd gen trucks. I suggest you post a truck profile listing the mods' to your truck which will help the TDR Gurus' in deciphering the problem. You say that you have a P1689 DTC, which if my memory serves, is a communication failure from the ECM to the VP44. If the truck will start and run normal I would clear the code and drive it. If there is a problem, it will come back.
Good luck...gregg
