I recently bought a 1980 305 El Camino, and I would like to know how to reset the check engine light.

Any help is appreciated. Thanks.

Welcome to ECC drizzt!

The check engine light can be reset by unplugging the fuse for the ECM for a couple of minutes. However, if the ECM detects a problem when you start the car the light will come back on.

You should pull the codes to see what is really wrong.

Disconnecting the positive battery cable for a couple minutes will work too...

For me, that will also reset the radio stations and the clock. That's why I just pull the ECM fuse.
