2000 STX 1100 DI Electrical Problem

[GTR]

I've got a 2000 STX 1100 DI that quit while idling through a no wake zone and would not recrank. Unit will turn over repeatedly, but will not spark nor will the fuel pump prime the injectors. There's no authorized Kawa dealer close; however, a local watercraft service center states that the control unit is bad. I have no problem with replacing it if it is actually bad, but I wanted to be sure it is bad before I did due its high cost. Has anyone seen this specific type problem before?

Thanks

Is the check engine light on?
Are you sure the fuel pump is not turning on? It could very well be a senor. Seams weard the ECM would just stop working.

i would make sure of what ultra said previously. if neither is working, it may be the emm.

I have got the same exact problem with the exception of the fuel pump and I'm not sure about that. I too have been told the control unit box but don't want to spend over a grand for a trial and error. I am going to take mine to a dealer to have checked. I will let you now what I find out, feel free to give me a call 816-739-1444 if any questions or if you figure something out I would apperciate it. Thanks Scott

If you have a check engine light, the codes need to accessed by a dealer or someone that has the Kawi s/w & cables. This is the only way to diagnose it correctly. However, no spark is a good indicator the stator, battery, or EMM is defective.

Yeah, everything was double checked. No check engine lights, no spark from the spark plugs and the fuel pump is not priming the injectors when the system is activated; however, as previously stated, the starter turns over fine when you hit the start button, batter is in good condition too. Have a feeling that it is the control unit but I figured that someone had run into the same problem before.

Scott, if you would, please let us know what you find out after your trip to the dealer.

Check and re-seat the fuses?

Check ground of coils or try to bypass with external cable between (-) battery and ground coil, I saw this problem on my old 2001 STX-DI, after I needed to rewire two ground wire between 3 ground center.

Ski went to dealer with the no spark issue. They hooked up their computer and as soon as they made the connection between computers it would blow the main fuse on the jet ski not allowing the computers to talk to each other. I've ordered a new computer so we will see if that fixes it.

Have you had any luck with your ski yet?

fuel injector #2 went out and shut everything down, Before this was found we replaced the computer, the stator, and neither one of those were broke. Is all it was was the fuel injector which kills everything. Good Luck...
