Problem has been repaired. Bad fuel pump. Replaced fuel pump assembly which I figured was the issue from the begining but wanted to troubleshoot and verify. The 20 amp fuse and relay (to fuel pump) located in main fuse box under hood were checked at the begining. fuse good and relay tested and checked out ok. checked wire harness that runs along door jams back to fuel pump located in access panel behind rear seat. Wires appeared ok and not cut in any way. Could not get volage at connectors. There are 2 connectors to fuel pump. One 3 wire and one main 4 wire connector, that contains a small black wire for ground, one small green wire and a large green wire. These green wires should have power. Back probed wires and had assistant attempt to start vehicle. With a good connection now to terminals, I had voltage at both wires on main 4 wire harness that plugs into pump. Voltage verified at pump, hence, determined bad fuel pump. Replaced entire fuel pump assembly and now good to go.
