01 nubira, only runs on 2 cyl. specifically cyl 2&3. No spark from coil controlling cyls 1&4. Replaced coil, no change. Checked wires, coil is not getting signal to fire. Changed computer, no change. checked wiring with tester, there are no open shorts in the wiring between coil connector, and computer connector. also checked wires from cam and crank sensors, they are also fine. ohm'd the sensors, and they are within range. Can you think of anything else to try?

Check the crank sensor gear plate.
Have you confirmed that sparks is missing or it is just not firing due to compresstion loss, fuel injectors or spark plugs?
