If you have spark but no tach, maybe the tach signal from the ignition back to the ECU & tach is broke/disconnected. If the ECU doesn't see a tach/ignition signal, it shuts off the fuel pump & doesn't fire the injectors.
Know how to check ECU codes? Normally, when the engine isn't running, the first code is 12231 for 'no ignition signal'. Crank the starter for several seconds, FIRST, before checking codes. Then check codes directly WITHOUT turning off the key. This way it is NOT supposed to show 12231 if your tach signal is OK.
