Hey I am looking at a sup for $500 the guy says it was running okay a week ago than he had to jump it to get it started, now it wont start at all. He says he can hear it turning over but it wont start. He thinks its the fuel pump but he doesn't sound like he knows much about car. I'm going to bring my code reader if I can get it powered up I was also thinking of maybe bringing my fuel pump if it is really simple to take out and maybe my battery any other recomendations on things to troubleshoot?
