Always a good idea to put year/make/model of the vehicle and the replacement parts as there are many differences between years.

For most years of seadoos, the ECU has to be flashed for the correct year and model and then married to the cluster for it to run. Typically it will crank but not start so it sounds like you have a communication problem between your different modules.

If you describe all the details in complete and exact information, I can tell what you need to do to make it run.

The security code for the cluster and the ECU have to match. Copy and paste the ECU security code into the cluster security code and then write it to the ECU.
