Ok, let's see. Assume your timing is ok on the gear unless it turns to a point a binds. Binding would be bad.
Check for spark, got that ...good.
Take a piece of vacuum line and run it off the metal nipple under the SC on the LIM. Put the straw of a can of brake cleaner in there and have someone crank the car.. do a few short bursts of brake clean. Does it run? Does your shooting brake clean help it start? If yes..check the maf. a bad maf can turn off the injectors.
Crank sensor is plugged in? Pull the connector and inspect with a mirror for any bent pins. Check the ICM connector. Should be snug.
