During the week I decided to do some "cleaning" up of my boat engine. Scrubbing this and that corrosion of sensors and what not. After cleaning up my oil pressure sensor switch connections I tried putting it back on and it seemed to not go back on like it should. The post the hex nut screws onto felt loose going back on.
So today when I took the boat out it ran fine for a while then would not start. The fuse on the fuel pumps was tripped. I reset it and the boat ran again, for a while then it tripped again. It seems to reset when I wiggled the oil pressure sensor wire (blue wire).
I'm thinking the ecm is not getting the signal it needs from the oil pressure switch and it's cutting the engine off because it thinks there is no oil in the engine.
