To add to KenB's reply, another place to check is the engine alternator voltage to the control board. There is a small alternator under the flywheel which provides an AC voltage to Pin 8. This voltage tells the control board that the engine is running by energizing relay K2 which then provides power to K3 which provides power to Pin 9 which runs the fuel pump and ignition coil.

Check the alternator voltage from Pin 5 to Pin 8. It should be 25-30VAC with the engine running.
