I know its not a quad just need engine help.
I got this bike 2 months ago brand new. Upon arriving i tried to start it, wouldn’t start. I started digging into it found i was getting no spark and electronic fuel pump was not priming. I got a new fuel pump, coil, and ecu. Still no start. There is power running to the coil just not coming out the other side. Also power going to the fuel pump just not priming. If i connect fuel pump directly to battery the pump works fine. Disassembled / reassembled kill switch still nothing. Checked all connections and fuses everything looked ok.
Im not sure if the two issues are related or not but it seems like something is blocking the power from flowing.
any help is much appreciated

 

First thing is to check fuse(s) and that all earths are connected, check both engine and frame are earthed. After that you need a wiring diagram. Whoever sold you the bike should provide some back up, so should be able to send a diagram, from this you can trace where power should go to after the ignition switch. At a wild guess I would say power isn't getting to the ECU but without a diagram you are going to be lost. Also it will be extremely complex electrically, EFIs are, it may be best to take it to someone expert at motorcycle electrics.
