thanks guys i changed the ignition switch block and the solenoid my wife keeps telling me to go back to what ford replaced and that was the fuel heater this is driving me nuts

Might be the ign. switch. Try cranking and have someone remove the small wire on the solonoid to see if it stops.

Too, late.

Have you tried unplugging the fuel heater and replacing the fuse, just to see?
