ignition 700 1990

"The under car fuel pump whirrs when I turn the key. Does this negate the crank position sensor as a problem ?"

No, that brief pump cycle only verifies that the pump will run. It's a special condition that doesn't relate to anything except the Fuel Pump relay being energized by the ECU in a unique way prior to cranking.
