Refreshed 20v blacktop first start..

[Mylesmck]

Well Lads,
I'm tryna start my engine and it kicks, but just won't "catch".... So it's getting fuel and spark, but not enough to idle or rev.

For context, it's been rebuilt with new crank, bearings, rings and gaskets. I've wired it with cops running off the oem ecu (for now, until I can afford a standalone). So it batch fires the sparkplugs which should be OK as the injectors are sequential.

Oil pressure is good, engine cranks without any wierd noises, I could feel heat on the no. 2 & 3 headers. I tried to upload a video of it trying to start but it's too big.

I'm wondering if the itbs need to be balanced... Should I do a compression test? Should I get a timing light, jumper the diagnostic plug and try to set the ignition timing?

Help!!!!!?
