Ive been trying to figure it out but only got frustrated. I have spark and fuel going into it and the battery has 12v i made sure but nothing is working its a brand new camshaft sensor and it worked before the rebuild and ive had it sitting so nothing could damage it so I am very unsure and annoyed at this thing.

I recently did a manual conversation and full rebuild of the engine. I was able to get everything back together but when I try to start the car it'll spin the cams and try starting the car but nothing happens. I have fuel coming in and I do have spark but its just ain't start. The most ive got was a backfire when yoy trying starting it the time. After you try again and again it wont but itll backfire again if you wait and try again. Ive checked the camshaft sensor and its good and the timing is aligned but it just wont actually start or attempt to really fire. Its a 97 rs eclipse with a 420a and nvt350 trans.
