Regardless, the pump motor voltage feed is on a PK/BK wire.. Think there is a 4 wire connector for 5.0, and 7 for 4.0's with the Press/transducer. Whats the wire color and tracer on the 3 wire connector your testing? If you don't have a voltage at the inertia, pull the fuel relay and check for 12v on the #85 terminal (key on), and then for a battery voltage (hot at all times) on the #30 terminal.. The terminal configuration is on the relay.. If you have 12v on the #30, bridge the #30 to #87 and that will run power direct from the power distribution box/battery to the inertia, and to the pump connector/pump if the inertia is closed.. If you have no voltage on the #30 terminal double check the fuse for a 'voltage' present at both sides.. Not sure, would have to check, but the earlier Exporers got their key on/#85 voltage through a closed PCM relay.. Either way, bridging the 30/87 should at least complete the power feed on down and run the pump if the fuse is good, and the motor itself proves out..
