I have a XP900 and it seems that the ECU has taken a crap on me. The fuel pump will not fire and it does not seem to want to trigger the starter relay well. It also is making my PC5 act all wierd, I just wanted to see if anyone else has had this issue?

Never seen a bad ecu, but seen plenty of bad PC5's. Have you tried removing the PC5?

No not yet. I am not sure how that would make the fuel pump not come on. Not saying that the pc5 isn't bad. I am going to take my over to a friends tomorrow and test it on his RZR. That should tell me if it is bad or not.
Does anyone know if an ECU off a 2013 will work on a 2011? From what I have seen it looks to have changed in 2013.
Just in case anyone was wondering. A 2013 ECU will not work on a 2011 2012. It throws an engine code. Thanks Tim for getting it to me so fast. I will put it up on Ebay now.
Hey Malibu mike I'm trying to diagnose a possibly bad ECM right now and I'm curious what you symptoms were. I just like you only dune and the car was running great a month and a half ago after my last trip and yesterday I went to start it and no go. Just as I turned the key to "on" the efi 20a fuse blows after a few seconds of the efi relay clicking rapidly. During that the gauge cluster, pcv and gauges will not come on. Fuel pump doesn't cycle either. Checked and swapped the relays around and same results. If I pull out the efi relay and leave all other fuses and relays in and turn it to "on" the gauge cluster, pcv, and gauges all come on. Any insite on this is greatly appreciated.
Mine seemed like the battery was dead and the fuel pump would not work. If you know anyone with a simular year rzr just put your ECU I their rzr and see if it does the same thing. I think mine shorted out so to a faulty realy being ran off the ignition
