91 lumina no fire

we dropped the front sub frame to change the tranny & when we did, we hitched everything back up & now no fire. it just cranks over any ideas. ty all

sorry its a 3.1 , with auto o/d.,

Basically, spray some carb cleaner in the intake, if it starts look for problems with the fuel pump fuse, feed to the relay, disconnected oil pressure switch can be a problem on some GM cars/trucks. If no start check for spark. All basics here. Post back.

check your wires to make sure you didn't pinch anything, and check the crank sensor plug, it's hard to reach (back of the block)and easy to miss when hooking everything back up.
