I wasn't sure of engine litre size? I looked at 4.3L engine. Did you check voltage and ground for the pump motor at the connector? Check the ecm bat fuse for voltage. Will the starter motor crank? There is an oil pressure switch in the fuel pump circuit. If you crank it enough to bring up oil pressure and the swtich closes, the fuel pump will run regardless of relay.
