1999 Seadoo GTX LTD no power on

Hi everyone!
I have a 1999 seadoo GTX LTD which will not turn on when a key is inserted, the dash stays dark, no beeps happen, but I believe (it has been awhile since ive tried) that if the solenoid is jumped it tries to start. I have tried a new to me DESS post (confirmed working), ensured the battery is in working order, and ensured all visible connectors are firmly clicked into place.

*IMPORTANT*
About a month ago I did get it to register a key and turn over (but not start), after unplugging and plugging back in the connector to the stator on the front of the motor, then after sitting for a day, the same issue occured, trying to get this thing running as I would like to ride at least a few times this season LOL

THANKS EVERYONE!!!
 
Probably the lanyard, I usually replace them in pairs, however the lanyard needs to be reprogrammed.

It could be, but I did test the lanyard on the 98, and it recognized it as a wrong key. Does this mean that the lanyard is still good?
 
This is what you can do I think, c I have done this to test lanyards or fess postd
Jump wire the post and lanyard from the working machine to the one with issues, if you get 2 beeps and it starts, you know it’s the post or lanyard or . I use retractable set 14 gauge wire that is on a wheel.
But I believe you will need a kit with wires on it,
Good luck

So basically use lengths of wire to jump the post from one ski to the other? Is the key programmed to the MPEM or the post? The reason I ask is that I tried a working post and still got nothing, so MAYBE there's a broken connection somewhere in the rear EBOX or a faulty ground, I don't think the harness is bad because it's really only sat and not ran since last season
 
Ok I think your not getting power what happens when you press the start button without the key on the gauges should power on

No guages turn on, the only weird thing was the one day I got it to start, i had plugged and unplugged the connecter to the stator, then it started, and the next day it was dead again

not sure if that was just a random event but all grounds seem connected and battery is confirmed working so I'm thinking SOMETHING wiring or rear EBOX related

(Basically pulled it out of storage beginning of season and it's been like this since then and was fine last year as far as i can remember)

Ok I would disconnect the plug going to the stator and look at it see if it’s got any corrosion on it put some wd40 on it put it in and make sure the wires plug in good and don’t push out of the plug. Also make sure you have all the little black wires hooked up on the battery along with the big black one. The stator plug is very important that’s where the MPEM gets it ground nothing will work if that’s not good 👍🏻
 
I inspected the connector to the stator, it appears to be all good as far as I could see (the pins on the stator side appeared fine, but am not sure how to take apart the connector to the harness to reseat the pins), i have also confirmend that if the solenoid is jumped, the engine will will turn over and try to start, but when a key is inserted there is still no power to MPEM, wondering if the stator ground is bad and i didnt see anything? or if another ground is faulty somewhere else 🤔
