    Start button turns over engine even with out key?

    97 sea doo xp. I installed a new starter. Tried to start it up and it fired and stalled. Its cold here in ct and it hasnt run in a few months. Primed it and fired again for a second. I took the key off to close the hood and walked to the other side of the ski. Looked inside and noticed my msd water injection timer light still on even though there was no key. Plugged my key back in and off and it shut off.. then.... now it will turn over with no key at all but will not start.. now when i put the key on it still turns over.. but my digital egt and tach wont turn on. No light on the msd water injection timer and wont fire. Just turns over.

    Any ideas? Im lost.

    Check your battery voltage. I am betting your low, anything less than 13.0 and some electronics don't work the way they should in the cold.

    Battery is fine and turns over nice and fast. With or without a key lol and now the key doesnt turn on the tach or anything for it to fire. But turns over mint

    Well start tracking down electric components. start with spark check,fuses. connections with attention to the ground. Have you worked on it lately? Do you have a multimeter?

    Done and done. Fuses fine. Connections fine. If there was a bad or poor connection i dont think it would turn over with no key either haha. I checked every plug. And wire in the machine. No spark. Because with or without the key. The computers and tach arent activating. But regaurdless of that. What rhe hell causes it to turn over even with no key all of a sudden.

    Have you pulled the connections on the MPEM to check for water. Have you opened the rear box to check for water.

    Voltage is normal. A bad dess post would allow starter function with out key? And with or without the key no electronics to activate allowing spark?

    I have had a ski do exactly what your saying, but when I checked the battery it was at 11.9 volts . Put in a freshly charged battery and all the problems went away. So where is your battery at.
