Question about 1990 Ford F150
Starter switch why is not making contact with electrical system
BOTH ANSWERS ARE GOOD BUT THERE IS A FUSIBLE LINK WIRE ON THE STATER SOLINIOD THAT MAY BE BURNED OUT LOCATE THE FUSIBLE WIRE AND GIVE IT A LITTLE TUG, IF IT STRECHES IT IS BAD MAKE SURE YOU REPLACE IT WITH ONLY FUSIBLE LINK WIRE

Woodstock's answers are good but he left out 1 other possibility. Since you don't mention whether or not the truck has ANY lights or if the horn works or not, the other possibility is that your battery cables may have too much corrosion on them causing your problem. Remove the battery cables starting with the negative terminal (the black one) and make sure it cannot touch the battery terminal. Next remove the red (positive) cable and make sure it does not touch the battery terminals either.
If you see some white gunk on either the terminals or the cables, you need to clean them. This can be done in different ways - use a solution of baking soda and water mixed in something you can dip the cable ends in and soak them until they stop bubbling. Then use a brush (preferably a wire brush) to make the inside of the cable terminal shiny.
Do this with the other cable also. With the battery terminals just pour some of the solution over them and follow the above procedure. You can also use cola soda instead of the baking powder solution.
Bottom line is that you want the cables and battery terminals clean and shiny. Reattach the cables to the battery (positive first) and tighten them down to assure good contact between terminals and cables. With an old toothbrush placing some petroleum jelly (Vaseline) all over the terminal and cable ends will help prevent this in the future.

I would start by looking at a blown fuse or perhaps a bad relay or maybe a broken wire! If not any of those not sure would say maybe the starter, but you indicated that your gauges aren't working which make me think of the items I recommended! Hope it helps! Good luck!
