No does absolutely nothing you can jump the solenoid and it will spin I did this with the old Mpem just to check the compression no gauges or anything the starter solenoid has power and has power coming out of Mpem to starter solenoid but no ground going to starter solenoid relay
Can spin by hand it’s not locked and compression is right at 150 on both cylinders when jumping solenoid
I checked all those even ran a jumper wire from the post in the grey box to the battery and engine
All of it checked out fine that was one of the first things I checked the gauges don’t even light up no beeps or anything if I jump the solenoid will turn over but no spark and the Mpem is sending power to solenoid but no ground at the two wire plug on solenoid
FYI - The gauge (only have fuel) on my 96 GTS don't move until I plug in the lanyard *AND* hit the start button. I know you checked it, but I do you want you to know typical/expected behavior of that model.
Good luck!
Also, I've seen a bunch of posts on the forum recommending against aftermarket MPEM, even new. Pulling a known-good, old MPEM is preferable to an aftermarket.

We’ll see my vin runs as a gts but I believe someone has put gti gauges in it as it has 2 gauges as well I bout a MPEM of eBay that was used and supposed good turns out it wasent so I ordered one from jet ski plus I’ve heard good things about them I’ve searched everywhere for a known good one and can’t find

What made you think the mpem was bad? Usually a no spark is when I would even consider being a problem.
You bought a used one and it didnt work. So now you are buying another one?
Did you confirm all the fuses in grey box are good?
IF someone tries to jump start it with reversed cables can blow the fuses.
I used to have several grey boxes with complete electricals somewhere. If they are still around maybe try to help diagnose your problem.

I know not to from previous skis guy wouldn’t listen to me I figuerd he fried the MPEM when he told me so I offered him 400 for it still can’t get anything to work no solenoid click no beep no turning over unless I jump solenoid but still no spark start button is good and so is the safety button I ordered a different MPEM so we’ll see supposed to be here Saturday I wish I had a wiring diagram of which wires have power when and ground

Does that mpem have a provision for any fuses? Did you confirm they are not blown? IIRC there is a 15 amp fuse on module that goes directly to the solenoid.

There is a small red wire attached with large red cable to one terminal on starer solenoid. Is it on the hot side?
