[QUOTE="Rmz450rider70, post: 1299910, member: 26357"] Update: I really appreciate the couple suggestions I've received so far. The time I've had available to work on the truck has been limited and spotty. I'm very grateful that I have a second car, however, this has made me realize that my car needs some TLC too since I always choose to drive my truck over it. Yesterday I rebuilt the wire going from the fuse to the relay, and the small gauge wire connected to the relay side that jumps over to the pull up side of the relay. That way I could be confident my problem wasn't there, and then move on to troubleshooting the wiring harness from there back. I tried to start her up after replacing that wire and she still wouldn't start.. I dropped the spare tire in order to access the plug for the Fuel Pump Driver Module. I visually inspected the wires at the plug and wiggled them to see if anything felt off. When I unplugged the connector for the FPDM a decent amount of sand came out of the connection. I blew both sides of the connection out with compressed air, plugged it back in, and went to go try to start her up. I turned the key and immediately heard the fuel pump. Vola! she fired right up!! I started the truck 3 times with no problem and then had to drop everything because I had somewhere to be and was already running late. Now then.. what was the problem? What came first the chicken or the egg? Was the sand in connection the reason it wouldn't start, and in addition to that the poor connection it caused was also a factor in fuse burning up? -Or- Did the fuse blowing out cause problems downstream in the wiring harness and me wiggling the wires around allowed said problem to make enough of a connection to allow the truck to start now? Once I get home in about an hour I'm going to: 1. Try to start it again without touching anything. 2. If it still starts then I'm going to wiggle the wires some more, disconnect and reconnect the FPDM connector, attempt to start the truck, then repeat the process at least a half dozen times in order to see if the problem resurfaces. 3. If I still can't get it to "crank but wont start" then I will just leave the spare off and drive it around for a few days, then recheck. I will update this thread when I figure out more information.
