Hi Scotty i have a 2008 Nissan rogue. That i had being fixed. For a blowed head. So we had the head shaved down. And put it back together and it doesn't spark. So we got a new camshaft sensor and still doesn't want to spark.

I assume is sparked before. If so, wiring or sensor was damaged check closely

Yes it sparked before i was able to start it up before. And i got a cam sensor and a new crankshaft sensor
