I just went through the same thing with my 2001 Tuaurus (Vulcan). Finally one day oout of the blue it finally ran. The Ford drive cycle doesnt seem to work effeciently to run the evap for some resaon. The NY State DMV website has a simple drive cycle to do that worked for me. Only takes about 5 minutes. I will try to find it and send it your way. Good luck.

Try the following drive cycle. It worked for me. i just had the same problem you are having and the Ford drive cycle just wouldn't run the evap monitor. This one did it. Let me know how make out. Good luck.

1. The OBDII drive cycle begins with a cold start (coolant temperature below 122
degrees F and the coolant and air temperature sensors within 11 degrees of
each other).
2. The ignition key must not be left on prior to the cold start - otherwise the heated
oxygen sensor diagnostic may not run.
3. As soon as the engine starts, idle the engine in drive for two and one-half
minutes, with the air conditioning (A/C) and rear defrost turned on, if
equipped.
4. Turn the A/C and rear defrost off, and accelerate to 55 mph under
moderate, constant acceleration. Hold at a steady speed of 55 mph for
three minutes.
5. Decelerate (coast down) to 20 mph without braking (or depressing the
clutch for manual transmissions).
6. Accelerate again back to 55 to 60 mph.
7. Hold at a steady speed of 55 to 60 mph for five minutes. Decelerate
(coast down) to a stop without braking.

Just wondering how you are making out with your evap monitor.
