I've got an '85 Ford L9000 with a Detroit 6-71 engine. Engine was running fine and I decided to pressure wash it this past Sunday. Truck sat until yesterday because I was doing some brake work on it. Went to start it yesterday and the engine was full throttle and ran away. I had to put it in gear and let the clutch out to shut it off. Any idea of what could be wrong or is it just a coincidence and an injector is stuck open. Like I said, it ran fine before I pressure washed it. Could it be possible that the pressure washer knocked a wire off? I don't believe the injectors are electrical; am I right? Guess I just should have left the engine filthy dirty. I took the air intake elbow off and covered it with a piece of sheet metal and tried it again with the air throttle down, and it smokes like hell with black smoke. Any and all advice appreciated.
