Help. Car wont start

Just replaced the Head Gasket, turbo, both chains, and catalytic converter. Now car wont start. It's an 08 automatic GXP. I have fuel pressure and I have spark. I found something about the ground on the front of the engine and cleaned that off. Any help would be appreciated.

Security system, air, fuel, spark, compression.

I assume you don't have a security light on? (Yellow pad lock symbol in the instrument cluster.) If you're really getting spark, then this probably isn't the issue.

We'll assume you're getting air (as opposed to having a rag stuffed in the intake somewhere).

Did you properly reconnect the injector harness (to the injectors and to the main harness)? Check fuses & relays?

Last thing would be to perform a compression test. The numbers will be off since the engine is cold, but it's an easy test and may reveal the problem.

Also check that the throttle body and MAF sensor are properly connected and that the throttle plate is actually opening.
