2001 gtx fri

[KIX157]

Hello! New here, and recently got 2001 gtx rfi Has no spark and when pressing start/stop button it doesn't turn over. Maybe someone can help with ideas what to check? Have checked the solenoid and starter both work. One ground cable was bad but after replacing it still have the same issue. Could it be the MPEM? Although I read on one sea doo forum that if it makes the two short beeps the MPEM should be fine.
I think it's 2001 gtx rfi, not quite sure though.
It's my first ski so any information about it will be helpful, thanks in advance

Have the battery load tested. Also test the start button. Have you tried jumping the solenoid with a tool to verify everything from the solenoid to starter is working right?
Send us a pic of the engine, someone will be able to identity it, also the serial number on the back of the ski , the last two digits are the year it was made. RFI means it has no carbs but is fuel injected.

Is the beeper working and if so are you getting 2 beeps when inserting the key?
On a RFI the coil is located under the seat mount. Make sure those plugs are in good condition and plugged in securely There are (2) plugs. The single black is a ground If I remember correctly so make you you have continuity when grounding to the engine with the multi-meter.

Hi. Thanks for the replies. I'll try to go and check these things today. I'm getting 2 short beeps when putting the key on. Guy who had it before me said it died on him while riding, after flushing with fresh water it started up but shortly died again. I'm thinking maybe it has to do with bad ground. Found a service manual yesterday so I'll try to go trough that and troubleshoot in order.

I would take the spark plugs out and look in the cylinder to see if there is any water in there, almost sounds like he flooded the engine with water! If you can turn it over by hand until pistons come to the top on each side.

Where are you from? That’s quite a view in the background

If I jump the solenoid engine starts turning over. Battery is brand new 12v 19ah. In of mode the voltage is 12.36v when jumping solenoid it drops down to about 11.98v.

 

[KIX157]

It's in really rough shape but I hope to get it running and freshen it up.
The loose red wire next to solenoid is one of the wires that go to main switch.
In second short video I turned on the diagnostic mode but after doing everything like the service manual says I don't get any error messages or beeps, so according to the manual engine should start
I will try to go trough manual and try to test everything I can in order according to the manual I'll try maybe this weekend if I will have the time.

I assume you've checked the voltage to the solenoid when you hit the start/stop button. That wire cold be internally corroded or a bad connection. I've dug some debris out of a plug on the Dess Post plug. You are getting 2 beeps so the computer is seeing what it needs to see. Seems you have either start circuit issues or the MPEM is not sending the signal. This is usually the point where I go in my MPEM stash and swap one out to see what happens. Do you have a friend with the same model ski?

 

[etemplet]

Did you take the MPEM box apart. I have found water in them in the past. I believe that ski has a CDI type box also and that might be your problem as well. Good Luck !

Have you had any success getting this running? currently working on an identical ski that only has 87hrs on it.

So I found that the ground cable from the battery to the engine block was damaged, swapped it and now I get the engine to turn over. But doesn't start yet.
Found a guy on fb who owned it about 3 years ago and apparently it's changed owners 2 more times since then, but by the looks non of them got it running so I suppose it's been sitting for about 3 years.
I have done compression test for both cylinders and I get 155psi in both, which is still good by the service manual.
I have good spark, but when trying to start im just getting some hiccups from the engine.
So now I'm thinking I will try to pull the injectors and check them, although after trying to start I pulled the spark plugs and there was gas on them. Another thought is to pull the crankshaft position sensor and take a look at that, maybe it's giving the spark at the wrong moment. That could explain the backfire I get time to time when trying to start it.

 

[KIX157]

I'm thinking to put the fuel injectors in ultrasonic cleaner. Don't know if it's a good idea though?

 

[etemplet]

Send the injectors to fuelinjectorman.com for a good cleaning and test.

Okay, so I got the ski to start, but it starts only when I take out the rave valves. Could those been the issue all along? they are pretty dirty.

 

[KIX157]

 

[KIX157]

With the rave valve installed it doesn't start

 

[burtshaver2021]

That horrible sound wouldn’t be the rave valves hitting the piston would it be?

 

[KIX157]

Nope, it's just the sound of exhaust coming through rave valve seating, cause I took one out.

That’s what I thought of right after I posted, good luck

You could also look in the rave hole and turn the engine over by hand and see if here is any damaged to the pistons/rings to verify they are not hitting. Normally they only hit if the engine has been rebuilt and they bored the cylinders out. Then you would need to cut the raves down a bit.

That just sounds like exhaust

 

[KIX157]

Did that when I took them out, pistons and rings looked quite okay, and I guess if they would have been hitting I wouldn't have 155psi of compression in cylinders

 

[etemplet]

Rave valves will not stop the ski from starting. By removing them you are creating a situation that is allowing the engine to start. I'm not an engine guru but if it starts with the raves out than the engine is overly rich. I'd check the shot on the injectors. I had a MPEM once that kept the pto cylinder injector spraying like a jet cleaner. Removing the raves changes the size of the combustion chamber.
