Had I seen this, I would have made a strong case for the fact that the LH 2.2 ECU does not fail, or does so very rarely. My usual guess is the injector relay or its wire plug. It is the only way to have air, fuel pressure, correct timing, and spark and still have no start. Two black relays, engine bay, one is AC fan, the other "radio suppression" or injector relay. Swap them, but be aware the connector for the relay degrades at teh plugs into a waxy mush, so you can have a good relay and still no start.
