2007 seadoo rxp no power

[mateo12344]

hi guys! I recently purchased a 2007 seadoo rxp supercharged and the ski has no power at all when key is put in, the only way I can get power is if I jump the relay myself, I’ve tried new battery, checking fuses/ connections, new dess, new keys, even tried a different ecu/dash, new relay, new solenoid, checked grounds, checked most cables connections to ecu for Connection, I am very stuck cannot think of anything else to try please help!

Start/stop switch/button?

I saw someone had a issue like that but the ski starts with the switch after getting power to the relay

I don't have the wiring diagram for the 07, do you have a mpem and the 30 amp relay in the fuse box? I am pretty sure the start circuit, dess post and start/stop switch are telling the ECM to supply the ground to the relay to crank not start. So you are bypassing those components of the start circuit by jumping the relay.

I have the 30amp relay in the fuse box both are working fine and the mpem was discontinued 2006 I believe, here are the wiring diagrams if it helps!

You need to test your relay circuits and make sure they are powered and grounded, also if the start/stop switch is stuck closed (normally open) it will act like what your sled is doing. Worst case scenario the ECM is not supplying the ground to the relay when it should.

@mateo12344 Did you get anywhere with this? I seem to be having a similar problem.
