the pressures appear normal. the pressure should hold steady for a few minutes key on engine off...when cranking the pressure will drop slightly..

other things to do would be as mentioned the fuel filter...also replace the fuel pump relay,and check the ground connections to the fuel pump in the fuel tank area,,these grounds and relays at this age become a problem...

make sure the battery is good [load test], and the connections are clean and secure..

another possibility would be an injector leaking / dirty...
