I did a heads cam swap on my vette,the car started and ran for a while with not many issues. I have driven maybe 2 miles, but now after it sat for about a week it wont start. It just pops and backfires through the exhaust. Any ideas?

 

Tune???????

 

Cam postition sensor

 

No tune yet,i want it to fire off before I load it on the trailer for the trip to the tuner. I would hate to get over there and it not start back up.

 

have the same problem !!!

 

just make sure all wires plugged back in. Not sure which one I had unplugged but it caused the car to run like sh&t. Any codes otherwise?
