ok so i noticed on my 96 PSD the part of the dash with my wait to start light and such was not plugged in, well i finally got off my *** and plugged it in this weekend. now my water in fuel light comes on ONLY WHEN I GIVE IT GAS???? i changed the filter, drained the system next to the filter and put rotella addititive but that light still comes on only when i hit the gas. i think the my sensor is broke! any sugestions?
