My 89' ford ranger will not pass smog here in socialist california. it has passed for 15 years since i've had it. the new machines indicate that the check engine light is'nt operating. i don't know if it ever did? what can i do?

Hi, it's possible the bulb is burned out or not making good contact with the circuit board. It should come on during the bulb check when you first turn the key on. Pull out the cluster and check the bulb. If it's good, see if you can clean the contact surfaces to get it working again. Or, move to another state where they don't worry about stupid things like a light bulb.
