2016 UFORCE 800 EPS randomly dies.
« on: November 08, 2018, 08:37:48 pm »
Hello, New to Forum, when riding my UFORCE 800, machine will die without any ryme or reason. Cranking it will not restart till you hear the fuel pump or fuel injection. Then sometimes dies right after it starts. Been to dealer and can't get it die. Has anyone had the same issues or ideas to fix? TIA

Yes, there have been some issues with the UForce's ECMs I would double check all the electricak connections..including the main 30 amp fuse holder as they also have been known to have bad internal crimps. If all is good, then try a ZForces ECM. Keep in mind that much of the EFI's system is low voltage and that if there is a bad connector, it won't show it like a burning or heated 12 volt connector. Look very closely and all the pins and receivers for a bent one.

You can look it up as easy as we can. 2016 ZForce 800 ECM.

But I would double check all other possibilities first..they aren't cheap...:)

My Zforce does this randomly, always slow speed and reversing. It always starts back up though. It does it less than when it was new

Yeah mine has always done this when I put it in to reverse then touch the gas. Not always..but most often. Always starts right back up. After I clean the air temp sensor it stops for a while..sometimes many months. Then when it starts happening again I pull the sensor and find air filter oil on it. Clean it again and it's all good again...for a while. :) I started squeezing that Unifilter with some paper towels after oiling to get any excess out. Seems to help...but it did do it once on our last trip. The sensor hasn't been cleaned sense last year though.

Could you tell me where the Temp Sensor is located on it? I obviously would like to go the inexpensive way before purchasing a ECM. TIA

Its the only sensor on the intake track. On the Zs it's center, top on the cross-over section.
