Hello guys ,
I will start this by explaining what is going on with this z6 2011. The UTV was stored in a container for 4 years and it was working before it stopped there. I went back in it , tried to start it after replacing the battery and the instruments cluster turns on with the speed , etc. I can turn on the flasher and brake lights , honk and use hazard. The problems is that the engine doesn't turn over , I cannot hear any "click" from my relays (fuel pump, others relay). Someone has given me his ignition switch to try it on , but it didn't work. I've bypassed the starter relay and it crank ( no start ). I've started checking for voltage at my fuel pump relay to see if it turns on , I get the 12v on the White/black but the Blue/Yellow is not triggering ( Trigger ground is coming from the ECU ). I got all of my 12v at my fuses , no voltage drop over there. I'm kind of lost in this research , I'm looking for some info to guide me.

Knowing nothing about the 2011 600, but understanding that all your electrics check out, I would look at any safety cut-offs to see if they are interrupting the circuit. The two that come to mind on my Z is the dash kill switch and the brake safety. After 4 years of storage, I'd be looking for signs of critter damaged wires too.

We did have one instance in here where someone replaced his battery and hooked up one of the power wires to the negative post; something to check as well.

I've pretty much "redo" a wiring diagram for myself since I couldn't really figure what was going where and which one was Positive or Ground. I've end up with 2 relay not getting trigger by the ECU itself. The fuel pump relay is getting 2x12v positive , 1 is supposed to be a negative trigger from the ECU when you start. The other one was the "ignition , starter relay , auxilary" , getting 2x 12v positive when one is suppose to be a negative trigger. I've jumped those 2 with grounds and I could crank + hear the pump working. I pretty much think that my ECU is dead inside

I've also checked the Brake switch to the Brake relay and I got all of my feed there. The shut off switch is working properly aswell when you shut it off , I lose all my feed.

check all powers to ecu / tried to insert elec. schematic for you , but won't load.....check page 11-4 of service manual
