A complete wiring diagram will show you what wire goes to what terminal.

Not to worry friend, when my car go sick i avoided going to mechanic looking for DIY_Repair when I found this website https://big-manuals.com/products/mitsubishi-l200-2005-2014-factory-service-repair-manual
and this book helped me repair it within an hour, all by myself!!!! It's amazing, no hassle at all

From wiring diagrams, schematic illustrations, spark plugs info, parts info, stepwise instructions, torque specs, error/fault codes, engine info, to every single minute parts, you get everythingg in there you can't imagine how detailed it is

After you changed ONLY spark plug wires?

I would say you failed to mark them before
you took them off & make a diagram or have
reference material & you put the wires on wrong
& now you have cylinder misfires & unburnt fuel
out the exhaust

From the timing belt to the transmission the fireing orders are 1234 One and three fired the same time 2 and 4 fire the same time. Pull all the plugs for the spark plug on them and lay them across the top of the motor with plugs in them you can see which ones fire at what time. The spark plugs need to be touching a grounded part of the engine to fire. This also will help you find out if you have bad wires.

(from left to right) The left coil runs number 2 and 3, the right coil runs 4 and 1

Your local Auto Zone can give you all of that information, they're computers will print out it for you.

you really do not need a diagram to locate the spark plugs. If you can see the high tension wires (thick electrical wires) connected to the distributor and to the to of the engine, just follow it up to the top of the engine where you can pull it out. It should reveal a whole in which inside is the spark plug. If your engine has a cover on the top (made of hard plastic), you may have it removed to gain better access.

Does the engine crank over but does not start or is it not turning over?
Are you getting any fire? You may check this by removing one spark plug and putting the plug wire on the plug. Then touch the end of the plug to ground, set it against the engine block or valve cover. Have someone turn the engine over while you watch the end of the plug to see if there is a spark. Remember do not hold the plug or wire because you will get shocked.
