2005 Sea Doo RXT Fuel Gauge Problem

[Mpincince01]

My 2005 Sea Doo RXT Fuel Gauge stopped working. Tested the sending unit and it gives the proper resistances. Tested the cluster by applying resisters inline, and the cluster also tests as good, and gives the proper fuel level readings with the proper resistance applied. All sections of the wire harness were tested for breaks, and all showed good continuity. So, I assume it's my ECU. Everything else works as it should, but there doesn't appear to be anything else in the Fuel Level schematic. Is there anything I'm missing? And, if not, do I need to replace my ECU, or can it be repaired by just having the dealership re-flash it? Any help would be greatly appreciated, and Thanks in advance.

Dealership can't reflash it, most won't even know what that means. I have seen this issue a couple times, do a search on here where I recall helping someone with the same issue a couple years or so ago. The only solution I've found is a new/used replacement ECU. Riva and some other performance shops can reflash but I'm not sure if that will even fix it. I suspect an internal failure with the ECU but it may be worth contacting them to see if they have resolved this issue before.

Thanks Bud, I appreciate the help. I guess I'll just pick up a new/ used one on ebay. At least my ski is before they married the ECU to the Console, so a lot easier to swap out. Thanks again.
