    1998 Sea Doo GS won't start

    I bought this ski a couple of years ago and used it very little. You've always had to jiggle the key a little to get it started. This year on the first time out my wife hit a wake and it died, I had to tow her in. So this is what I've done, one replaced the post, and 2nd replaced the MPEM (aftermarket that kills the security system). Using a multi meter I can open and close both the kill post and start button before it hits the MPEM. However I get no reading after the MPEM. Also the power is coming into the MPEM and the fuse in the MPEM. I can jump the solenoid, not that it matters because the start button doesn't make it that far. Is there a sensor or something going on that would kill the start button in the MPEM? This is going to drive me nuts. PLEASE HELP

    If you're still having issues let me know those are easy modules to bench test and the harness/wiring only has a couple functions to get you to the point where the MPEM should be cranking the engine.
