RX7 won't start, tried everything I can think of.

Hi I own a 1991 rx7specs below. In late winter I was having trouble keeping the battery charged. I just parked it for the winter and when I went to start it it wouldn't turn over. Jumped the battery, still no start. Replaced plugs and pulled the egi fuse to clear out any flooding. Still no start. You can smell gas and the original set of plugs were soaked due to trying to start with less than full charge. I checked the air filter, fine. If it has air, spark, and fuel I am at a loss. It would be virtually impossible to tow due to where it sits so this is up to me. Kinda new to the rotary so simple is good please. Thanks!

If you have fuel and spark, she should run. Maybe try a new set of plugs, old ones might be fouled. Hows the gas in it?

I put a new set of plugs in already, gas should be fine. Definately full. Plugs are DEFINATELY in the right spots. Could this be a timing problem?

If you have fuel, air and spark then your timing is off. Phone around to see who can run a diagnostic on the ignition module. Then take it off and have it tested.
This is going to sound silly, but first reset your computer. Turn the key to the run position and disconnect the negative battery cable. Wait a few minutes, some say 30 seconds others 2 minutes. Leave the key in the run position and hook up the battery cable back up. Then try to start it.
After you change any electrical part do this. It resets your computer to the factory specs.
