I assume you've changed the spark plugs? Measure continuity in the wiring harness between the injector connectors and the ECM. If you have a noid light, check to see if you're getting pulse signal to the injectors. If both are good check compression and leakdown.

I actually got a noid light yesterday to check for a pulse and when I did, the car died. Could there be a short somewhere?
