Unhappy Won't start

I've recently swapped engine and gearbox on my 2003 986 S. All fitted nice and neat no major problems with the swap. My problem is it wont start. It turns over but wont fire. Current situation is its on a ramp wheels off roof down. I've tried locking and unlocking and all the what my mechanic thinks is the obvious stuff but just wont fire up. Have you experts any idea of what to try next

Are you getting fuel? Are you getting spark?

My simple answer: Go back, as many times as it takes, and figure out what you failed to connect, or connect properly.

Do you see any codes that have been thrown? That might help focus your efforts.
