First, does the check engine light come on when you first turn the key to RUN, but not start it (for the bulb check)? The one in my van is burned out, so if I have a code I wouldn't know it. 😂 If it does, then diagnostic system is working fine and we have a no code driveability problem.

You would know something is up. Along with the CEL staying lit - there is a warning chime when you start the engine. I know this because when my cooling fan relay was temporarily disconnected my CEL would light up and I would get an audible warning chime.
