1997 Ford F-150 Q&A
1997 Ford F-150 Question: pcm fuse in power distribution box blows when ignition is turned on.
Start tracing wires from fuse to module to find short circuit. Module least likely suspect but can remove pcm wire connector to see if short is inside unit, short should not be present if computer is at falt. - pushrod
should there be continuity between fuse terminals in power distribution box with large fuse removed?
