i have a 95 z28 136k miles
just did a rebuild on the engine put cc503 cam new springs ported stock heads im in the break in process now so been driving for about 3 days today it wont start

it turns kinda sparks sounds like almost something is reaching the exhaust and dies out what do you guys think it can be

my bestfriend says it could be the dead plugs or a knock sensor

Did you get a tune done at the same time?

I don't think a tune would cause a no start condition.

Could be. Only one way to find out, start spending money I'd still put money on it being the opti.

Take your valve covers off and check to see if you have any loose rockers, and make sure you have gas in the tank. Those have been the two reasons my car wouldn't start a couple of times. Worth checking the rockers anyways, to make sure it was buttoned up good.

thank everyone it was the coil the opti had been changed but like said earlier im going to just start spending more money
