2007 Seadoo GTI SE 155: Jet ski was running rough. Pulled the ski out of the water in running condition, maybe misfiring on 1 cylinder. Went to check spark & change plugs. Pulled all the plugs, loosely grounded them. 1st plug had yellow/blue spark. Then machine died. Now no beeps at all with key on post. Guages light up, no error codes. Fuel pump does not run. Have checked/replaced battery, fuses, start/stop switch, starter solenoid. Confirmed ECU is getting 12v from red/white power wire. Did checking the spark fry the ECU? Or the ignition coils? Is there a way to test the ECU to see if that's my problem before buying a used one & getting it married to my guages? Thanks!!
 
Does the ski turn over when you hit the start button? You said that fuel pump doesn't run, maybe that was your original problem and pump is dead?
 
When I hit the start button, the starter relay clicks, but that's it. Engine does not turn over, unless I jump the starter solenoid. Also no spark at the plugs while jumping the starter solenoid even with the key on post.
 
Load test the battery,,,a poor spark will come from a weak battery,,,anyway,,,something easy to remove from the equation,,,you could have 2 issues.
 
Thanks to everyone for their advice. My problem was no beep with key on post. Fuses were all fine. Replacing starter relay, starter solenoid, battery made no difference. Also verified ECU was getting power through wire. So ended up replacing the ECU and jet ski runs now.
