    Talking HELP! 07 RXP 215 wont start. no spark or fuel injector pulse

    Hey guys. So im new to the Sea Doo game and ive got a big problem.

    A buddy of mine sank my 07 RXP. The engine hydro locked, and the oil was all milky, but that was taken care of. New plugs, emptied the intake manifold, changed the oil until it was back to legit color, then changed the filter. The ski started up perfectly and idled fine a few times, then out of nowhere the 5th time or so, it just died. I noticed the fuel guage was empty so we filled ot up. The thing wont restart now!

    Ive got a fully charged battery and a jumper on it, it just cranks and cranks. Ive already put a new cam sensor on and swapped with a running ecu/key from my RXT. Still wont start. Theres no spark and no fuel injector pulse. The fuel pump is good.

    Any ideas on what to try next? Im lost! Thanks in advance

    Check the fuses..

    Don't jump start a ski. That's the fastest way to cost yourself a Butt load of $$$$

    The dash cluster has to be married to the ECU for it to run.
    Dealer has to use BUDS to do it.

    Unplug the dash harness by the hood shock,& start it to verify
    That's the issue.

    Youre saying to do that on the Rxp with the rxt's ecu? And ive been through the fuses time and time again.

    Yes, the ECu's are the same, just the RXT ECU dosent have VTS activated. The 06+ RXP, and T's have to have the ECU married to the dash cluster. U can just unplug that 6 Pin connector for the dash (by the hood shock) and try to start it.
    If they need to be married it will not start, unless that connector is unplugged. (just a test really)

    Okay. So ive tried everything mentioned so far, and after disconnecting the crank sensor and blowing on it it started up, ran for a few seconds, then died, and still wont restart now. Any ideas? Maybe the connectors are just wet or maybe the crank sensor is bad? Does anyone know how to test the crank sensor?

    It should be showing a PO code on the dash if a sensor is bad, and also should have a long beep when u first put the key on. Does it display any codes?

    How do I make it display the fault codes? Dont I need the dealer computer?
