My check engine light in my pickup has never worked. I never really cared until today because I just found out it is an automatic fail for emmisions testing in CA. I checked the bulb and it works fine. The truck has over 200,000 on the odometer, but only about 30,000 on the rebuilt engine, that I just recently did a head gasket change on. The light does not even work when I try the shorting the terminals in the ECU for diagnostics. Any ideas? I would take it to someone, but my finances are pretty shot at the moment.
Thanks
