The pump may not be burnt up at all. First, make sure you have voltage at the pump by testing the electrical connector at the pump. These connectors are nortorious for becoming loose and causing all types of connection problems. It is best to just replace these connectors. Then clean up the fuel pump ground connection located just before the fuel tank -- it is the black wire that terminates to the frame cross member and breaks out of the harness just before the fuel tank. If there is no voltage at the pump, check the fuel pump relay under the hood. If it is real hot - replace it. Next, be sure that you have proper oil pressure. If you do, the oil pressure sending (OPS) unit may be faulty. The OPS unit will shut off the fuel pump when it is faulty or when there is no oil pressure. It does this by breaking the circuit at the fuel pump relay. Check for control voltage at the relay.
