Here's a video on changing your rear spark plugs. 2007 Kia Sportage EX rear spark plug replacement

If the trucks turns over and does not seem like the battery is dead I would assume it is spark or fuel. Check spark plugs to make sure they spark. Pull one plug at a time hold it against side of engine and have someone turn the truck over for you. You should see bright spark from all spark plugs. If you do see spark then check your Fuel Pump to make sure it is getting power and is opperating correctly also check your fuel filter to make sure it is not plugged. Good luck, Hope this helps.

assuming it is the 5 cylinder engine there are no plug wires. there is an individual coil for every cylinder the spark plugs will be directly under these coils

You should see a spark plug wire for each spark plug. The spark plugs are in the cylinder head. You have to unplug the plug wire first before you replace the plugs. Be careful as to not damage the plug wires when removing them. Be carefull not to get dirt into the cylinder when replacing the plug. Do not overtighten the new plugs. I can't remember which side of the engine the plugs are on, on your truck. You truck has the inline 5 cylinder I think.

Use owners manual to see if your spacing on the spark plugs are correct and the torque for each spark plug must be exact to prevent mis-firing. the owners manual will contain all the information you need to know about doing basic maintenance on the car.

Should black coil assembly going across top of engine,remove and plugs will be located underneath.

I am assuming that you are asking about the spark plug gap. Hope this helps

GASOLINE ENGINE TUNE-UP SPECIFICATIONS Year Engine VIN Engine Displacement Liters Spark Plug Gap (in.) Fuel Pump (psi) Ignition Timing (deg.) Idle Speed (rpm) Valve Clearance (in.) MT AT MT AT In. Ex. 2005 8 2.8 0.042 50-57 - - - - HYD HYD 6 3.5 0.042 50-57 - - - - HYD HYD

This is the 3.5L inline 5 cylinder engine. The spark plugs are at the top of the engine. They are covered by a hunk of plastic called the "Air Intake Resonator".  Remove the plastic. Carefully pull the ignition coils from the spark plugs. Unlike most other cars. The Colorado has a coil on every plug.  This boosts ignition power, but, every coil is expensive. Do not harm them.
