Located in under hood fuse/relay center. Owners manual will give fuse locations and identification. Make sure dome light is not turned off by dimmer switch

the tail light uses one of the contacts in the socket so if its not working on the one side then check for lose of power on the tail light wire from the socket back to the wiring loom at the rear of the truck for a bad wire.you can check for a fuse but I believe there is only one fuse for both tail lights.

Most likely the sending unit needs replaced.

you can also find it @ #1 coil..same purple wire , probably easier to get to !

It greatly depends on what type of vehicle it is (you didn't indicate make or model). However quite a lot of vehicles have an actual over ride switch or interior light kill switch. Some are in the overhead console (has a light with a slash thru it). Others are in the rotary switch for the dome lights, if turned on way to the max it shuts off the lights. Others are simply a push button on the dash near the headlight switch, in the center console or even on the steering wheel lever. If it doesn't have an over ride switch then its most likely a blown fuse, which will need further diagnosis.

If a crank sensor is bad, it would either start or not start.
If it is missing, then the coil pack or ignition module is likely faulty.
You can hook a voltmeter up to the wiring to the sensor and crank the car and make sure you are getting the same 12 volt reading on the sensor and the wiring as well. It will take 20 cranks for a system to relearn

Disconnect the battery, disconnect the wiring to the starter solenoid. Remove the 2 bolts going up thru the starter, into the block.

There is no way to put it back together. The system is spring loaded and if it is now in pieces, it was time replace 3 months ago. The tensoiners can be purchased at any auto parts store. They come with a new bolt and are very easy to install. When you put the belt/new belt on, make sure you can read the writing like holding a book in your hand. This will make sure you have no squeeling even with a new belt. Let me know if you need anything else.

The new starter may be binding with the flywheel, if there was a shim that came with the new starter it should be used. If the fuse never blew before the starter was replaced I would bring the starter back and exchange it for another one the starter itself could be faulty right from the remanufacturer, it is most likely drawing too much power to do its work therebye blowing the fuse. Check all wires to the starter ensuring that no wires are crossed or touching a metal surface.

Good place to get a vacuum gauge hooked up and identify problems using that tool. Without the gauge, check your exhaust and see how much if passing through the converter. You can do this by testing the temperature of the exhaust before and after the converter making sure the converter/exhaust isn't restricted. As the vehicle warms up a bad converter can cause the symptoms you are describing.

P1860 = TCC PWM Solenoid Circuit Electrical P0740 = Torque Converter Clutch Circuit/Open and P0785 = Shift Timing Solenoid "A" Maybe spurious codes, I can't tell.
