fuel pump issues
Pretty sure the ign sw supplies the power to the PCM power relay ( in the CJB) that provides the power to the fuel pump relay which is in the Central Junction Box. Once the fuel pump relay closes it provides power thru the inertia switch to the fuel pump.It would seem a good place to start and easiest to get to , would be to check for power at the inertia sw. and work your way from there.
