I replaced the ignition switch, ignition switch housing and I reset the security system. The truck ran fine for a couple of days. Today truck won't start, gauges aren't working but drive selector and mileage are working.

I have seen a shorted instrument cluster cause a no start issue. We need to check a few things, first when you turn the key on without cranking the engine over can you hear the fuel pump inside the fuel tank for about 5 seconds?

If so, let's check for spark which this video will help with:

Also, let's run the codes to see if any are stored. Go over this guide:

I would also check the fuses.
