Fuel pump relay has power with key on. I am thinking it's a solid state ground from the ECU. I don't see a ground with ohm or diode function, but if I hook up the meter where the relay coil terminals go, I read voltage with key on. When I touch the relay to the terminals, the voltage reads zero, like the relay is shorting it out, but the coil measures 75ohms, just like the others. Any ideas?
