Hello, my name is***** the check engine light come on for bulb check when first turning key on?
Have you tried a different key? Are you getting any type of security system warnings on dash? Thanks.
Does the black/white wire going to coil have power while trying to start?
Considering what has been replaced it sounds like the ECM has failed. Verify wiring between crank sensor and ECM are good, if so replace the ECM. Crank sensor should produce around 1.5 while cranking. Here is a wiring diagram to help with testing. Let me know if you have questions, thanks.
