Need help! 2004 Seadoo sportster 4tec turns over but will not start

[Brianrph99]

It starts first try before I bring to the shop for engine and driveshaft alignment. got it back and won't start at all. Battery is full charge, new spark plugs. Check all over to see any loose wire, nothing even check all fuses. What the hell happen? Any opinion will appreciated.

What engine work was done to it?

Engine and driveshaft was out of aligned because broken engine mount. that was it, no engine work.

Man that sucks sorry to hear! First thing I would do is get it back to the shop and find out what they did and get them to fix it.

If you are on your own.

Are you getting any check engine lights when cranking? You could pull a coil and spark plug, ground the side of the plug to the block and crank it to see if your getting spark. Do that for all three cylinders, post back. While cranking with the one plug out you should also be able to tell if injectors are opening by the fuel vapours coming from spark plug hole. If your getting no spark it could be that either the crank sensor is disconnected or camshaft sensor is disconnected. The ECU uses both of these signals to fire coils (but you would see a check engine light in this scenario). Dont understand why the shop wouldn't just do the simple ... does my customers boat even start before I call him to come get it ....

EPIC FACEPALM!!

Well, on my speedster, the crank sensor wire ran under the PTO. I wonder if they got it caught and broke the wire when messing with things. I would bring it to them and tell them it ran when I dropped it off, don't give it back until it runs again.

It turns over strong but no fire. Have not check the plug for sparks yet.

K check the spark test, I beleive on your engine the Cranksensor is inside the MAG cover. Right beside your ECU will be the Crankshaft Position Sensor connector, Camshaft Position Sensor connector and your MAG connector (three yellow wires).

What should i look for on the wires or sensors. And since the sparks wires are so short, how do i reach the chasis for spark test. Thanks

Problem solved! Turns out fuel pump deactivated so the shop connected the buds and reset it. Starts right up. Thanks for all your help! Life is good again.
