So i brought a Nissan Max 06 wit 220k miles for 2k didn't feel like a 220k car. No check light it needed breaks/ alignments just little things. A week later my check engine light came on for a cat converter but the car still ran like a champ. One day getting gas at costco i put 91 in the tank then later went home. I tunred the car off but not way off i was still in the car listening ti music. When i tried to turn the car on it didnt start. It cranked but didnt start. I thought it was the battery but the next morning i jumped it and it didnt start. I know that battery was good because the radio turned on. Could it possible be the fuel pump need replacing or something else?
