My Montro cranks but will not start - Montero Sport Mitsubishi Cars & Trucks

There could many different problems. do you have any check engine codes? if so have them checked out, because a sensor may have failed causing the engine not to start. then you need to check the fuel pump. stand by the fuel tank and have someone turn the key on, but dont start the car. listen very closely you should hear a small electric motor run for about 5 sec. if you dont hear anything, check the fuse and the relay. when you turn the key on the relay should make a fairly loud click. if no sound is heard the relay needs to be replaced. if you still dont hear the motor your fuel pump has failed.
