I'm new and not really sure if anyone can help, but any advice is better than no advice. the fuse blew to all the gauges in my dash, so I replaced it. I went to start the truck, and it won't start at all. The gauges all work now, but it just won't start. It's not the security system, as the light is still blinking and is not steady. Wondering if it might be some sort of electrical surge problem... I really don't want to have to take it in if I don't have to just for them to,hook it up to the computer and make me pay hundreds for it. Any help please!!!

 

If your security light is flashing with the key on, then that means the ignition is not recognizing the key. Therefor it looks like you will need to take it to the dealer and have them reprogram it.
But seeing how the fuse blew, its possible you could have something going on with your Instrument Cluster. What fuse it?? Fuse number?
