2009 CRF450r won't start
Posted: Mon Jul 22, 2019 9:08 am
I have a 2009 CRF45r that won't start. It has a new big bore cylinder and high compression piston. The head has been completely reworked and has new valves, seats, guides and has been ported and polished. New Hot Cams cam shaft and a new crank from Hot Rods.
I disassembled the top end and inspected every thing. I did find the cam wasn't installed correctly, so I installed it properly.
When I try and start it, I only get a random pop out of it. I removed the tank and put power to the fuel pump. It ran and fuel moved out of it. I removed the fuel pump and inspected it, I found it to be a later model fuel pump.
Not sure how to test the injector or the ECM.
Anyone out there had this kind of situation?](./images/smilies/eusa_wall.gif)
