when i removed the fuel pump relay and direct jumped the power circuit, the pump turns on and gas flows. therefor the control circuit is not actuating the relay? We tested two other relays and they aren’t the issues. We tested for voltage and that isn’t the issue. We checked grounds and there were loose ones and we tightened but still nothing. Something isn’t giving the relay power. We are thinking PCM? The pcm is also making a quiet “dog whistle” sound with the key off, and with the key on, it gets slightly louder.
