Engine problem
2003 Ford Taurus V6 Front Wheel Drive Automatic 40k miles

The engine keeps running after I turn it of and remove the key. It is not the ignition switch that test ok. Is there a relay that might be bad. Removing the Batt term will not shut it off either. The only way to shut it of is to remove the big blue fuse in the fuse box. Pretty sure its a relay problem but do not know which one.

Thanks,

Jim

I would swap out the PCM power relay here is the location, its sounds like it is stuck on. Check out the images (below). Let us know if you need anything else.
