The injectors may be clogged, did you check those?

Air fuel and spark are the holy trinity of starting. Get these three with proper timing and it will start.

Do you have spark?

Can you try to jumper the DME relay to hear the fuel pump running?

Can you check fuel pressure at the rail?

Is the AFM plugged in?

Will it start with starter fluid?

Is the rotor in properly?

Verify the firing order from the distributor to the spark plugs.

How long has it been since it ran?

Have you checked compression on the engine?

When were the timing belt / balance belts last serviced? When and how many miles ago?

Answers to any of these questions will help narrow down your no start issue.

Good luck.

Yup - what Ky914Newbie said! Check also reference sensors... and smacking the fuel injectors with a small wrench to loosen them up as old fuel has probably gummed them up.
