I have a 1997 Eldorado touring coupe that the fuel pump has stopped working I have replaced the relay witch did not do anything checked the fuses and could not find any blown fuses. So I replaced the fuel pump with an ac/delco unit and fuel filter and the car started right up and I let it idle for about a half an hour shut the car of let idle again for about 10 mins and shut it off. Then I went to take it for a ride and after about a half a mile and the fuel pump stopped working. I have checked my relay and fuses agian and they seem fine. I was just wondering if any has any suggestions?
