Ok. I tested my IVR and it checks ok. I checked the number 11 pin on the instrument panel connector with switch on and Im getting 11.6 volts. If I disconnect the oil press lead at the sending unit and connect a dvm to it and ground Im getting .12 volts. Check temp send unit Its .07 volts and fuel sending unit is .08 volts. Something has to be going on somewhere, I should have 5 volts on everything with my SS IVR!
