If the main power relay was sticking that might cause run-on, but I'd 
suspect a mis-wiring problem just as much.

When you turn the key ON, you should hear a click and a second click 
about 1 second later. If you reach under the dash and feel the fuel 
pump relay, you should feel both of these clicks.

If you turn the key ON and then OFF right away you should hear and 
the feel the second click as soon as the key goes OFF. If there's a 
delay, that's the main power relay sticking.

For the record, I can imagine that one of these relays could stick, 
but I've never seen it happen.
