Why wont my 2000 Mitsubishi Montero Sport start? This is the first time its ever happened. It shut off on me while driving on the freeway. I already changed the battery, checked the relay fuses, fuel pressure, and battery cables. The truck cranks but still does'nt start. What else could be keeping it from starting up?

you must determine if its spark or fuel that you are missing do you have a tach in truck if so does needle move as you crank engine?if it does you have crank signal . can you scan it for codes that may point you in a direction reply back and we may be able to figure it out. you may suspect a crank sensor also they go in the earlier models. reply back if you need any othr possibilities

Had same problem on MMS1998 3.0L LS. Car would run fine and then engine would die in the middle of the road. It would crank( hear the starter turning the crankshaft) but wouldn't start. I cranked it over 10 times each time up to 7 seconds until the battery ran out of charge and it would make only a clicking noise(not enough amperage left from all that cranking with starter solenoid) the clicking noise is your fuel pump relay. 349000 miles on the same engine. regular maintenance close to factory recommendations. Turns out that no starts are caused by 2 main issues. 1) spark plugs(ignition, coils, rotors, etc.) or 2.) fuel delivery(worn fuel pump caused by unchanged fuel filter, dirty fuel tank causing excessive filter clogs, injectors clogged) How to fix? get a repair manual for about $30.00 for your model and do a tune up. 2.) Check fuel pump diagnosis with fuel pressure or do Scotty Kilmer recommendation to determine which is the problem fuel or ignition. It could be that the battery just died on you. They lose charge even when everything is off; slowly that is.2- 3 years typical duration. In this case jump the vehicle with a friend's car. Turns out my vehicle had a fuel pump and fuel pump relay burned out. replaced both with fuel filter...car works well now! Keep learning and don't be afraid to look under the hood and read those diagrams. What seems complicated begins to get easier little by little. That is how I saved on repair costs so can you!
