Please help me!!!! I have a 96 discovery 4.0 that left my wife stranded. After getting it home, I found the fuel pump ran for 5 seconds and cut off. No pressure at the check valve on the fuel rail. I removed the fuel pump and it works fine. fuel filter was clear. put it back together and it started. After 5 minutes, it dies and have no power to the fuel pump after 5 seconds. Don't know where to go from here.
