    Arrow 2003 Sea Doo GTX185 continious beep with all sensors unplugged

    I recently bought a 2003 GTX185 it is not supercharged anymore.
    I have ran it about 14 - 16 hours the first thing that happened is the ski wouldn't start, so I unhooked the batt and hooked it back up and it started. I replaced the key and DESS everything seemed to be fine until there was a low pitch continous beep that was unnoticeable during idle on my last trip The beep got louder so I unplugged the speaker that was about a 8 hour trip trouble free. I trailered the ski home and flushed it. It sat for a week and when I put it on the water it needed a bit of throttle to start once she started she was running normal then cut off on me about 1/2 mile down river full throttle. I couldn't get it to start or turn over for the life of me, if I crossed the starter solenoid it would kick over but not start.... until I pulled any fuse that would cause a code it would then allow me to start the ski.
    Now some times she fires up fine and runs fine but some times she needs some throttle to start and will die on full Rev (all on trailer and hose)
    No codes and I still have that loud continous beep.
    I pulled all the sensors and ohmed them all good and if I pulled the temp sensor plug off with the ski running the continous beep gets 3x louder

    Any ideas? Since I have replaced DESS and key,, tested the sensors and checked fluids idk where else to go
    Bad mpem? I want to take the ski out but don't want to get stranded again
