So had my engine rebuilt by a local shop. When we tried starting it up it wouldn't turn. Changed out the cam sensor I believe which helped but now its only working on three cylinders if I understood correctly. My mechanic checked all the relay's and fuses, put on sparktech, but it's still having issues with one cylinder. Anyone ran into this problem before or have any guess' on what to try next?

Trying a crank sensor now see if that helps.
