Pulled the two connectors with Key ON to ignition and fuel pumps energized....Nothing happened. I checked that resistor and I don't see any corrosion on the leads.

Is the relay one of the metal square boxes under the fuse box? I wonder if I can switch the one from my 88 300TE as I know that functions right as a test?
