Check that you have pushed the spark plug wires fully home on the spark plug. If it's not turning it could be the solenoid that connects the battery to the starter motor when trying to start or simply a flat battery. Check battery first, check solenoid by listening to a click sound, check starter motor for connections check any related fuses.

There is a switch/sensor on top of the transmission that tells the ECU what gear you are in, it's a cheap part however it will often NOT throw a code, it's possible that this part is defective, this will also throw your transmission into LIMP HOME MODE, which is not fun it will feel like the transmission is bad when it is not. Also check both your input and output speed sensors as these tell the ECU what engine rpm is and what the transmission speed is relative to which gear you are in if the OD light is flashing these may be suspect, also relatively cheap and easy sensors to replace. Get KIA brand parts as aftermarket parts may not be calibrated properly.

by can't find the fuse, you mean you can't find one labeled as cigarette lighter? Or can't locate the fuses?
Visually check for a blown fuse, if none is found you have to assume that the device is broken.

First you need to know what kind of vehicle you have.

Apparently there is a tensioner that is not keeping the belt taught and it is not centered correctly on the pulleys. Or the pulley itself could be cracked warped or nicked.. Check out all the components carefully. A small nick or crack can cause the belt to chafe and run off the pulley and snap.

Year?

Check and replace if it is not working properly all mechanical relays will make noise when they click once to engage current to the load side of the circuit.

Easiest way is if you have another working coil pack and switch it out with the suspected faulty coil pack. Say you have a problem that is with the coil pack that covers the 1-3 switch it with the one that covers 2-4. If the problem does not switch to where you put the faulty coil pack... it's not the coil pack. Replacement coil packs can be found at an auto part store or if you need a cheap replacement you can usually find one at a junkyard.

Inside the boot between the coil and the spark plug.

There are 3 progressively difficult and expensive steps you can take. I have to assume that the Mentor is the same as a Sephia. First: Check the level of fluid in your brake/clutch canister. It MIGHT have 2 separate canisters (like the 1995 Sephia.) But I doubt it. Second: Check your hydraulic clutch cable and the unit at the transaxle. It may need to be bled. Third (and most expensive): Replace your clutch and pressure plate. This is the most expensive as it requires removal of the engine. I hope this helps you find the source of your difficulties.

Get it scanned for errors. The VSS or the speed sender unit may be damaged or not seated/fitted correctly.

Overdrive blinking is usually a transmission problem.

Here is the link to the official Kia site for service manual data: https://www.kiatechinfo.com/ . I've used this site before and was not required to pay a fee, but not sure if still holds true. This official site has diagrams of virtually the whole car and also electrical systems, etc. It should also have the diagram you're looking for.

Go to google and type each one in separtley and it will tell you why and the causes Jeff.

You need to take the cylinder head off to change the head gasket, check how straight the cylinderhead is and see for cracks in the head. Knocking can imply that the water has blocked the piston and the connecting rod has been bent--> see the height of all pistons.
