Question about 2003 Ford Focus
Sounds like the cars computer is bad to me.Usually called PCM or ECM. You could try a reboot of the computer by disconnecting the battery for a couple of hrs. Then you would have to drive a while to see is it is storing the info.

Same problem here. Test result printout says that OBD monitors are not ready. The guy asked me if I recently disconnected the battery because that action resets the computer and if that happens you have to drive your car anywhere between 50 and 100 miles and then redo the test. Well in my case it has to be something different as I did not disconnect battery. I read it also may be an electrical problem that causes resetting the computer.

By failed Emmissions you mean it failed inspection? If this is the case you got some bad gas somewhere. If you ever had the vehicle in Europe then you most likely will need to have the exhaust system replaced as they test from the tail pipe. This could also be the Catylitic converter. If you are talking about the check engine light going off it is most likely an O2 Sensor that needs replaced.

A service technician will
turn off the dashboard "check engine" light after most repairs. This
resets the vehicle's emission system components to "not ready". The
status remains "not ready" until the vehicle's computer has had adequate
time to review the repaired component. This happens after the vehicle
is driven for a period of time established by the manufacturer.
If the vehicle's emissions system status is "not ready" when it is presented at the E-Check station during the initial test cycle,
a tailpipe emissions test may be conducted. If the vehicle is
transferred to another test type, the vehicle must remain on the
different test track until the vehicle passes the emissions test or
receives a waiver. For example, if the vehicle undergoes an OBD II test
and fails, it cannot be downgraded to a tailpipe test on a re-test; the
vehicle must pass the OBD II test.
For initial and subsequent tests, if a dashboard light is on when the vehicle is presented at the E-Check station, the vehicle will fail the test.
How can the vehicle status be made ready?
When a vehicle is driven through its normal drive cycle, the computer reviews the emission control
system and if the vehicle was properly repaired, the system resets itself to ready. A normal drive
cycle includes operation at both cruising speeds and in stop-and-go traffic for up to a couple
weeks. This process should be followed before bringing the vehicle in to be tested.
