clutch replacement, now won't start

'91 c/k 1500, 350 changed the clutch, turned flywheel, reassembled and now it won't start. It turns over and tries to start but won't start. The crank turned a little while removing the flywheel maybe timing problems?

Info for first time clutch mechanics. DON'T PINCH THE WIRE BUNDLES BETWEEN THE TRANNY AND THE MOTOR, it shorts out the ecm.
