Pull the relay again and check it per the 89 manual, vol1, pp14-88 and 14-89, which requires some application of power to check voltage/continuity with relay(s) energized. Power to fuel pump is on in ign start via power form ign to relay. Power to fuel pump is controlled by ecu when ign is in run. No power to fuel pump in ign acc. position. It is instructive to examine the relay wiring from the wiring diagram at the first of section 14 (the MPI section).
