Take the distributor out and set the engine 1 cyl. to top dead center, put the dist. back in with #1 firing! Popping indicates timming problem! Or check your wires, you may have crossed a few of them!

Suggested Repair

Remove the distributor, set cylinder 1 to top dead center, and reinstall it so it fires on cylinder 1. Popping indicates a timing problem. Also verify the spark plug wires are not crossed.

Conversation Summary

The owner of a 1991 Ford Mustang GT 5.0 replaced the valve cover and intake gaskets and removed the distributor, marking its position before reinstalling it. After reassembly the engine cranks and pops but will not start, though fuel pressure is okay. The expert says popping indicates a timing problem and advises setting cylinder 1 to top dead center, reinstalling the distributor so number 1 fires, and checking that plug wires were not crossed.
