My dads truck is the same make and model as mine, 2002 2500 4x4 completely stock...Throwing the P1693 and P0216 codes... i have a sneaking suspicion that the vp-44 is bad and was wondering if replacing the lift pump would possibly solve the problem? or would it cause damage to the new one and we would be back in the same boat? as far as driveability if we didnt do anything for the time being will any more damage be caused to anything else? Thanks :banghead:
