This reminds me of a trip to Colorado I made a few years back. Stayed at a ranch up in the Rockies to go horseback riding. Anyway I come out of the rental one morning and see some guy with a car in pieces all over the parking lot, I mean the trunck was emptied, hood up and tools everywhere. Looked like he had pulled an all nighter. The guy was swearing up a storm about the piece of crap car not starting for no good reason. I looked at all the crap he pulled out of the trunck, looked at the ruts in the road coming in and bingo. Fuel switch is the first thing I think of because it looks like he would have bottomed the car easily. The guy goes ,"Huh?". So I lean in to the truck, hit the switch and say try it. Car started right up and the guy freaks....he spent the next couple of minutes throwing tools into the woods and throwing a fit...later on that afternoon after I got back from some riding he came over and apologized for freaking out (did'nt bother me a bit) and brought me a couple beers...lol.
