2008 Black Scorpion won't start
fropappy posted a topic in Centurion Boat Maintenance, Performance, Troubleshooting
Took my 2008 Lightning out a few weeks ago before going on a family vacation. It fired up in a couple seconds. Ran it for maybe 5 minutes and then took it home and changed the oil & filter and cleaned the dist cap and rotor. (I replace or clean the cap & rotor every year, so this is very routine) Took it to the lake this weekend and it would spin over, but wouldn't hit a beat. Kill switch is working great. When I pull it, the lights go out and starter will not engage. Put the clip back in and everything electrical seems to work, including the needle on the oil gauge. I had this happen a few years ago after I let a shop change the oil. They had just lost their ability to do Mercruiser warranty work when they dropped Centurion, so they sent it across town to a Mercruiser dealer for diagnosis. That was a major clue that I was using the wrong dealership. It was also my last time there. The other dealer took 2.5 hours to diagnose a wire that had been knocked loose from an oil pressure sensor. Original dealership was billed, not me. I never found out where that wire was. Showing 3/4 tank of fuel. I think I hear the fuel pump run for a few seconds, then shut off once it pressures up. Hard to tell over the noise of the perfect pass. I spent over an hour checking every wire connection I could put my hands on. Been working late this week, so I haven't had a chance to check the normal fuel/fire/air. Hope to catch a break Wednesday after work. I still think it will be a single wire connection that I knocked loose during the oil change. I'll report what I find.
