Mitsubishi Montero sport problem

Changed battery in 2004 Mitsubishi Montero sport all lights work but want turn over what could it be

If the wires for the battery are reversed it probably would not start as the brain would be fried. But easy to check, the positive wire from battery would go to the fuse box and another one to the starter. But in your case it sounds like a clogged catalytic converter. If it starts and dies wait 15 minutes and if it starts againonly to die in a few minutes it's going to be the converter. Remove the o2 sensor bank 1 sensor 1 and allow exhaust to come out the opening. If it starts and stays on then you know you need a new converter. Good luck
