Sounds like your axle seals have leaked out all the fluid. Take it to a garage and get a free estimate on it and they will check your axle seals.

Try checking the Trans fuse in the fuse box with the key on engine off to see if there is any power there. I do this with the fuse installed and use a test light to probe the back of the fuse. If ok you will have power on both sides. If you don't it is more then likely the ignition switch. There are dealer bulletins on this were they bypassed the ignition switch with a relay or just replace the switch. If the fuse is ok and has power you need to disconnect the trans connector and see if there is power to terminal E if I recall with the ignition on engine off. If no power there the wire has an open and this would have to be located. The most likely cause for this is the Ignition switch and I have replaced many for this problem.

Make sure battery has a full charge and battery connections all good. Any fuses in the diagram, test for voltage, some are hot all the time, some go hot with the key on. Use a digital multimeter across battery posts, everything off, the generic spec for a full charge is around 12.6 volts. Leave the leads hooked up to battery, have a helper turn key to crank, how far does it drop? In my opinion it shouldn't drop much under 10 volts, I wouldn't argue with 9.6 volts.

This is the most common problem on these engines that will cause every issue you just mentioned.

The problem is not the fuse most likely but the reverse light switch on the transmission. If it is an automatic the reverse light switch is part of the large switch that sits under the cable that shifts the transmission gears you select. If it is a manual it is located on the side of the case of the tranny. The interior lights are on a different fuse, do they come on at the head light dome light switch? Has the bulb been checked. I do not have the owner's manual on file due to the age of the truck, sorry.

Make sure battery has a full charge and battery connections all good. Have a helper crank it while you visually check for spark at the spark plugs. Does distributor turn when you crank it? If spark everywhere, check fuel. If you have a carb, mechanical fuel pump, sometimes you can take fuel supply line loose from carb, aim into container, bump the engine, see if gas comes out, if no gas have to back track. If there is gas, take the air horn off carb, depending on the carb, you may be able to remove air horn w/o removing carb, see if any gas in float bowl, if no gas, maybe you need a carb kit? Any vehicle needs fuel--spark--compression, right amount at the right time.

sounds like you need to replace the column stalk

Ignition 1 fuse drives many things. Look in your owners manual to see what it supplies. All of them need checked.

Hi, you need to provide more detail as to what happens

If you have fire at the plugs, it should or act like it wants to start. If it doesn't look at timing.
