Tilting the engine forward is a pain in the butt and risks breaking/stressing lines/connections. Still a pain, but easier, is removing the alternator. Disconnect the battery. Remove serpentine belt from the alternator by slacking back the tension pulley. Remove the front bolt on the alternator, tilt the alternator back to access the rear bolt. Once alternator is removed, access to the plugs is still tight, but you can reach behind the engine with the necessary tools (you will need extensions for your ratchet wrench) to get to the plugs. Just finished this job about 10 minutes ago. No wonder the car was missing on my 1990. Found gaps to be .055 - .075. For my year and model (3.1 sedan) gaps should be .035

The engine can be moved forward slightly.
Remove the spark plug wires from your 2004 Chevy Malibu spark plugs. Remove the old spark plugs with a 5/8 deep well socket, by turning the socket to the left. Reverse the process to install the new spark plugs.
One reason a 1993 Chevy Lumina may turn over but not start could be the battery. It may also be the spark plugs.

you are not getting spark. this could be from a bad alternator, bad spark plugs, bad spark plug wires, or bad engine coils. The spark plugs and wires are the cheapest so try putting in new ones of those first.
