I'm sure this not a new question but I just can"t navigate the site. So,this deemed to be the quickest way to get heard...... 1992 Explorer suddenly stopped cranking and now all I get each time I turn the key, is a click from the starter relay located on the right tire well wall, next to the battery. I checked the battery charge and tightened the connections. Still just a click. I jumped the relay by jumping it but still only get the click. I swapped out the relay with one from another Explorer and still.... I removed the starter and jumped the solenoid and both worked just fine. Question: Could it be the neutral sensor switch?
