I chased a no crank, no start issue this week. In the end the culprit was a bad ignition switch but I replaced a number of parts that were aged and worth replacing. So now the truck has a new battery, new starter, new fusible link, new battery cables, new NSS plug and the ignition switch. Was a pain to trouble shoot but a good excuse to take care of some of the other stuff.
