Well if your check engine light is coming on your getting power to the ECM, here is two checks, first check for power at the coil (first diagram, should be 12 volts), second check the crank sensor for a pulse while turning the engine over. It is powered up on the grey wire. The crank sensor will stop your ignition if its not sending a signal to the ECM.
