I have a 95 camaro with a 3.4 liter engine I had put a new camshaft, timing chain and gears but still won't run. If there are any sugestions please, I'm open to them. I would also like to know if I would have to change anything if I was to decide to swap that engine out with a 3.8 liter.

 

Test your ICM, and check your spark plug. If you have problem with your timing chain, hold the gas down to start it.
