At first i thought it was the battery. I tried to jump start it and at first it didnt work. I then pressed on the gas pedal and it started right up, but after releasing the gas pedal it shut right off. i then tried to hold the pedal down it stayed running but as soon as i let off it shut off again. the jeep also smelled really rich. im beginning to think its either the fuel filter or the fuel pump but im not sure.
