no start

Hello Seadoo experts, I'm having trouble diagnosing a no-start problem on my buddy's 1994 GTS Seadoo. For context, it has the 587 engine with oil injection. It was running very well when we picked it up a few weeks back, with 150 compression in both cylinders! However, after riding a few times...

I have a 1996 sea doo spi recently I rebuilt the carb and afterwards the jet ski will only start if you prime the fuel line each time. After priming it it will run good and has no problems until you turn it off and let it sit for about an hour then it will not start again. If I turn off the jet...

So I picked up a 97 GTI 720 on the cheap that appeared to have fuel issues. I checked and verified it is getting spark. The fuel lines are black and look newer (not the grey tempo lines), and appear to be free from the dreaded green goo, so I assume someone must have already replaced all the...

Good afternoon all, I recently purchased a 1996 Seadoo XP. At the point of sale, it fired up immediately and beeped twice as normal. Seller mentioned it had not beeped once for him just recently, but it went away and suspected it was a DESS issue. Before taking it to the lake, I had swapped...

Hello Seadoo community. I've been struggling with my 1994 GTS. I replaced my starter solenoid and stop button, and now I am having the following issue: -only way to start is to have lanyard in, press green start button, and then the "stop" button. Then I release the starter once it starts...

I rebuild an xp, whole engine, most components. Lost the OEM MPEM in the mail so I got an aftermarket one. Seems to work, it beeps twice when key is on and will turn over fine. I have no spark or gauges though. Replaced coil, starter solenoid, stator, and flywheel, I have no idea. Maybe the...

Hello, So I am restoring a 95 Speedster and recently installed two re-maned engines. One fires instantly and the other will not even cough. The no start (starboard) engine has 145-150 compression, double checked rotary valve timing, good blue&white spark, and good fuel. Two new batteries, timing...

Hey guys, I have a 2019 RXT 230, the throttle body went bad so I ordered a new one and just installed it. When I tried turning it on, I get a “check key” on the screen and I’m not allowed to do anything else. It does not turn on and a weird ticking noise starts. Only way to get rid of the...

95 XP does not crank with start button, dash turns on and then turns off It DOES crank by shorting solenoid, and also DOES crank on its own (only for a second) when key is attached, and only when grounding the MPEM to the stator for the first time, otherwise the stator connector must be...

Hello, So I have a 1997 seadoo gsx with a 787cc engine and it was running well up till last year. I just redid the carburetors, got a new starter solenoid and battery. I have also checked both the ground and other wiring. So the problem is when I plug in the key there is no beep for one, but all...

Good morning everyone. I am having some issues with my 95 seadoo XP 717. It started with a simple bad starter. I pulled the ski replaced the starter and went out for a test run. I had absolutely no power and blew a huge cloud of blue smoke. Shut it off next thing you knew it wouldn’t start...

Hey everybody, I got a 1996 GTI at the beginning of the summer and it ran great all summer and then I went to take it out during Memorial Day weekend and it does not beep when I put the key on the post and doesn’t even crank over or even click. Battery is fairly new I got it less than 2 months...

I have a 1997 Challenger 1800 with the dual 787 Rotax engines. I ran into a problem with one of the engines (left) starting then stopping after approx. 5 seconds. It was helpful to have one engine running fine as it allowed me to swap spark plugs and verify I still had a problem. In other...

We purchased a Seadoo challenger 180 from an individual a couple weeks ago. Started fine for the seller. Got it home, went to start it and nothing. Seller had left the all on switch on.(for over a week) So we charged the battery back up to 12V and still nothing. Not even a noise. -It’s in...
