Re: Trying to start my LS for the first time.

It will need a good strong battery, so start there. Definitely check to make sure the injectors are working. Clogged injectors from sitting happens all the time and are a cause of a lot of no start conditions on many first time swap starts. Also, as Greg said, hook up the MAF. When starting them on the floor, I usually just duct tape the MAF directly to the throttle body, it's not optimal, but it works.
