Ls2 engine swap won't start
 

Please help.
I installed 05 gto ls2 into my 1967 Camaro convertible. I used the gm performance wiring kit with there computer. I had a local machine shop change the 24 tooth reluctor wheel to a 58 tooth. I also changed the crank and cam sensors to grey sensors. Just found out that the upper timing gear was different so I changed it from a 1x to a 4x gear. I can not get it to run. I have good fuel pressure and spark. It seems as if the timing is off. I am getting worried that the machine shop put the reluctor wheel on wrong. Any ideas or thoughts would be greatly appreciated.

Sometimes those wiring harnesses for the cam sensor have the wires crossed.
