    Bri, I am new to the EFI deal, but wont the throttle cable adjustment keep it from getting spark? What about the water temp sensor?

    Snap the throttle a couple of times and see what happens.

    Yeah, That Was One Of The First Things I Thought Of. But This Boat Didnt Have Any Freeplay On The Throttle That I Would Have Adjusted Out To Begin With

    Nah, the TPS (except seadoo @ WOT) won't kill fire,......The kill lanyard in right?<---had to ask! Only things that will cause no spark conditions across all 3 cyl, are start/stop switch grounding the CDI, faulty CDI, faulty stator. I would bypass the start/stop switch at the elec. box, If that's not it It is time to break out the meter! What was The boats original problem?

    The TPS wont kill the spark but the off throttle sensor will (efi model that is)
    If you look were the cable meets the TBs you will see two adjuster screws one is idle and one is the off throttle sensor.

    Mikel70 is correct on the throttle. If its too tight, it won't start, we ended up having to fix mine by adjusting like he said. But you did get it to start and run on the hose for 25 minutes, so not sure what could have changed from then till now.

    Exhaust heat sensors could have gotten unplugged or ripped apart.

    Check the little rubber grommet that seats in the throttle cable at the finger throttle. If it comes out, it will not let it go back to idle. snap the throttle a couple of times. I had this problem a couple of months ago on my 03. mid life cable crisis?
