Rebuilt KA24E won't start. Ideas?

[8500dollaGSR]

Like the subject says, it won't start. Vacuum lines are set up correctly according to the FSM. Fuel lines are fine, injectors injecting, sparks sparking. The motor turns over while you crank it but that's as far as it goes. Anyone got suggestions as to what it could be? (I wouldn't be surprised if we forgot something stupid, but as far as I know it isn't.) Thanks in advance for all of your suggestions.

check your basics! do you have spark? Fuel? I recently had the same problem on my blazer. turned out the distributor was off one tooth.

It's funny you say that. If only you'd have been around a couple weeks ago. We got the KA running perfectly as of lastnight (except for a vacuum leak). Turns out the shaft that drives the distributor was off by a tooth or two. Thanks for the insight.
