I changed my fuel pump and fuel filter, the car started and ran for about 30 miles, now it won't start. It sounds like it is just not getting any fuel. It just won't turn over. I did hear some noise, so I think the fuel pump is working, but when it came in the mail, it was not packed in box tight. Not sure it could have gone out that fast. I also had changed the relay switch before we put the new pump & filet on.
