So what else could it have been on my Xterra that was causing it not to start? Do you really think they would screw me so bad as to remove a $240 alarm/starter, just so they didn't have to cover my warranty work?

I always assumed that a professional installer (of an alarm, or a stereo system, etc) would solder, use wire nuts, or crimp connectors for the wires - not just twists and electrical tape.

I suppose I am having a hard time seeing as to why Nissan would try to screw me over that hard, just so they wouldn't have to do some warranty work???
