Im curenntly running a LS turbo setup, but decided to swap shortblocks cause my rings are bad, so i swap a new block in, and car dont want to start now>>>

Theres fuel,spark, timing is good, just cant figure out what it is, i also checked all fuses, everything good...

ANybody have a clue why the car doesnt start, basically everything in the car is teh same except for the flywheel which i doubt that would not make the car start, by the way flywheel is of a 91 b18a, i nko its for cable trannies but my pressure plate bolts up.....
