Hello all

I am having some starting issues with my 2012 Ruck. I pulled the motor to replace what I thought was only the exhaust rocker arm, but turned out the cam sprocket needed to be replaced too. So, I replaced the cam, sprocket, bolts, both rocker arms, and put the correct shims in. Put everything back together and now I can’t get spark. Turn on the key and you can hear the fuel pump working, but press the start button and all I get is a single audible “click” coming from the battery box. Thought the battery was done so we tried to jump it off only with the same results. Could this be my battery? I replaced it back in March. Could it be my starter relay? Bad connection? If anyone has any experience or advice on how to get this thing going again that would be great.

Thanks.
