    Vehicle came in with blown engine. Rebuilt engine. Engine rough start/no start. No spark on cylinders 1,2,4,5. Reassembled timing chain assembly after advised to do so. Same issue.

    Yep check ground straps. Have also seen some problems while surfing around about wires easily being pulled out of cam sensor connectors.
