2000 sea doo gti, dess shows to be good and key shows to be good but no beeps and no start.

[LeeRiker]

I bought this sea doo about a month ago and everything was fine. I had a motor malfunctioned and had to remove the motor and fix it. When the motor was reinstalled the security system no longer works. All electricals check out fine,, the dess checks to be fine, the start button checks to be fine, I've checked every fuse and every ground and they all check fine. My mpem is not blowing any fuses but I have also tried two other mpem's with their keys and still no power to the start switch. This is the first sea doo I've ever had and by all the searching I've been having to do because of sea doo's security system I've come to the conclusion that sea doo's system sucks to the hilt. There is no way sea doo should sell any crafts with this sorry of a security system. It does cut out on theft because nobody can start their own sea doo!
