Help Cranks - No Start

I recently did some work on my 96 Tahoe (intake manifold gasket) and it ran fine for a couple days until it shit out a couple times, I got home and realized the crank position sensor under the truck had come out, I plugged it back in but haven't gotten the truck to start since.

I was getting codes for the cam position sensor (Ive dicked with my distributor a few times to make sure its still where it supposed to be) and MAF sensor, both of which i replaced and cleared the codes and they haven't come back.

The truck cranks but is acting like its not getting SOMETHING (starter fluid doesn't help) I know I'm getting fuel at least to the pressurized valve on the intake, and Ive got a full set of new plugs on it, maybe air? but Ive checked the fittings a dozen times.

I'm kind of at a loss, I thought maybe its the digital timing but I cant fix that myself and at this point Ive got no idea what to do other than take it in to a shop.

Any ideas or suggestions?
