Problem started 2 weeks ago. Three engine lights would come on when the truck malfunctioned. (1) Water in Fuel, (2) Wait to Start & (3) Service engine light. I've replaced the Injector pressure control sensor due to the fact there was oil seeping out of it. Once I unplugged that sensor all lights exstingished but the rig still stalled! I'm new to the deisel world but fairly mechanical. Any suggestions would be greatly appreciated!
