Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

You may need a voltmeter to check if power is going into the turn signal switch. Start at the turn signal fuse and see if power there, with key on.

look for the relay for the fuel pump/filter. disconnect electrical wires then reconnect.

nothing can be done other than what your already doing. 3-4 clutches are gone. thats something i seen everyday for 7 years working in a trans shop. only other option besides buying one is a rebuild. sorry.

This sounds like the auto locking hubs have gone out. They will sometimes make a ratcheting noise and then seize up. This time of year especially with the colder weather they will lock up when the grease gets old and hardens. The best thing to do is to replace them with a nice set of Warn manual lock-out hubs. There are some special sockets you will need to do this repair so it might be best to take this one to a shop.

probly a wire connection somewhere you missed when you put it back together

under hood fuses are located near the battery and on the inside wheel panels and fire wall. and are well named.

check all the wiring harness connections under the dash as it is possible that you may have partially separated a connection and the connection is now not complete.

Cranking and not even trying to fire is usually a fuel pump failure. First be sure it is quiet at the vehicle area. Battery is fully charged. Set in vehicle, radio & a/c-heater off. Turn key to on/run position for 3-5 seconds there should be a faint sound of electric motor (fuel pump) running. Turn key off for 10 seconds & try again. No sound of it running? Then next simple check is to have a person crank the engine while you hit the bottom of the fuel tank in center area with a hammer. Repeatedly hit it with solid hits (not too hard, you do not want to damage the tank) while cranking. If the engine starts the cause is the fuel pump motor failure. This requires to remove the fuel from the tank & lower the tank to replace the fuel pump. You must get at the level below 1/4 tank to safely handle the tank. If your engine did not start & you do hear a fuel pump 3-5 second prime then you could have a ignition failure. The most common is the coil wire corrosion in the boot and the tower of the coil. Check this at the distributor also. Also check all spark plug wires for corrosion. Best to replace these parts if corroded. If you do not replace them next best is to wire brush and seal with wheel bearing grease or ignition dielectric grease. Use grease on new parts you are replacing also. Sometimes the grease you add causes the boot to seal & air in the boot pushes the boot back off a little. The boot needs to be released of the air in it. Slip a very small screwdriver under the boot while pushing it on then there is a way for the air to escape. Chris ASE Master certified sense 1979

change your oil. if you have the wrong oil for your environment the cold will make the oil too thick to circulate and the engine wont start. I’m happy to help further over the phone at https://www.6ya.com/expert/christopher_64bc1c93be5190d5

run fault codes and look for a TCM problem or torque converter clutch fault.

Chevy's and GMC's were notorious for the headlight switch failing. as for no start, we need more info.

Does it turn over fast or slow? Or nothing at all.

Check the mass air flow meter,, on the air intake hose. ONLY USE AIR FLOW METER CLEANER! First I would check the air filter. sounds like the engine is starving for air. Check all your vacuum lines also for leaks. Make sure all are attached to where they go. Also a possible dirty throttle body !

no never on GM
