Im not sure what is causing me to have trouble starting myMontero Sport. ... 2001 Mitsubishi Montero Sport ...
Typically if your control module is bad, you won't developed a "localized" misfire, meaning on just one or two cylinders. So rule out that you simply got a bad part. Have you done a routine tune up? Spark plugs, wires (or coils), fuel filter, etc.? Typically you're going to want to start with plugs when diagnosing a misfire condition, followed by wires or coils (if it has a coil on plug set up). If you haven't, try that first.
The coils get power from the ecm. I would check all the ground wires between the body and the engine. Even if you just add a few. Take a wire around the same gauge as a lead cord, put two ring terminals on it and use some of the screws like a bracket hold down bolt on the firewall and a bracket on the engine. Make sure you clean the paint off of the area the wires will be contacting to make a good connection. If that doesn't help, you may have a bad ecm sending too much voltage to the coils.
I just did one the other day. There are three coils. You can determine which one is bad by using the number one spark plug wire and an old spark plug. Put the spark plug in the wire ( while it is still in the coil) and ground the plug against the engine block. Make sure it is grounded solidly to metal or you could get a nasty shock. Have someone start the engine. Look at the spark. It should be fat and blue. Turn the engine off as soon as you have seen the quality of the spark. Pull one of the wires from each coil in sequence and move the number one wire to that coil. Proceed as above. The weak coil(s) will have intermittent spark, yellow spark or maybe none at all. Once you know which coil(s) are bad remove the two small screws at the ends of the coil. They hold the coil down. Pick the coil straight up, pulling the contacts out of the ignition module. Set the new coil in place and screw it down. Both towers spark every time the coil fires so reinstall the wires in either spot on a given coil. Good Luck
Starter solinoid is stuck and is not engaging the starter into the flywheel. You need a new starter but for the moment, get a mallet and hit the solinoid, the small cylinder like thing on the side of the start a few good times then try it. If you can't get it to go I suggest getting a new starter and changing it on the spot, it's pretty easy. Cheers bro.
