This may require hands-on diagnosis.
The Engine Control Module (ECM) controls fuel and spark. There are several system tests and continuity tests that need to be done to make certain the ECM isn't the problem.
Have you go a manual?

. Check all under-dash fuses with a test light or multimeter.

. Test/replace the Ignition Control Module and coil.

Replace the crankshaft position sensor, which controls both spark and fuel injector pulse.
