91 won't start

This '91' will not start, but will turn over (no spark) Have tried the following:changed ignition module and ignition coil, check all fuses and computer codes. Tried spray starting fluid into intake manifold, still no change. Check and tested battery (Auto Zone) changed battery cables and terminals. Timing belt was changed last year-car has only 92,000 miles (belonges to elderly family member)
Maybe computer????
Any one has any other ideas I would be grateful
Thanks

sounds like you've got a bad MAF, (mass air flow senser)

Do you have any power going in to the coil? I'm wondering about the ignition switch.

Check the Dark Blue wire going into the coil. It should have power with the key on. Check 15A "Engine" fuse. Also looks like the smaller wires going to the battery ground terminal are ignition grounds so check them.
Looks like the 'EEC Power Relay' might cause this to but I'm not sure where it's located.
