Hi howard lee
Did you disconnect the battery some time before the smog test? Did the smog inspector say he got a "system not ready", EGR testing not complete? If so drive it for another week or so and retest it.
can be a bad cat /sensor / computer or wiring usually takes about a 100 to 125 miles on most vehicles to reset after clearing a code dead battery or replacing battery but thats if all systems are working properly if it was reset because of a code and that part of system hasnt reset than more than likely a problem with a component or system from original code
The system has to see a wide range of conditions before a smog test can be done. On most brands you have to drive at least 50 miles, at various speeds including stop and go, let it idle for 5 - 10 minutes, and run at freeway speed for at least 25 miles. It also has to reach normal operating temp of 195 degrees.
Have the charging system tested, it sounds like the battery went dead on you from a charging system failure. Charge the battery up enough to get to a local Autozone, Sam's club or O'reilly auto parts for the testing, it is free .
In order to set the monitor it the drive cycle 2 trip criteria that means you need to have a cold start up and reach operating temperature then another cold start up with a operating temperature reached and the drive for each one is part throttle hold for 2 miles and a decelration for the catalytic to get ready.when the cat is ready the evap runs.If you are loosing monitor at key off and everything reset you can see the referee let them smog it. The EGR and EVAP are almost impossilbe to get ready
