1993 Jeep Grand Cherokee mileage: 75,000. My jeep would not stay running. It would start but not stay running. It has been broken down for seven weeks and has had five fuel pumps put in, all from Chrysler. It has been at a dealership service department for three weeks and four weeks before that at another garage. The fuel pumps all go out within minutes to a couple of days after being put in. The dealership seems to be at a loss. They have checked out electrical problems. What could be the problem?

There may be a faulty fuel pressure regulator that is causing the fuel pump failure. In addition, if you have a poor ground connection grounding the fuel pump, the fuel pump will fail.
