Fuel Pump Relay question

[Kneale Brownson]

My 4kq and 200q20v both have grounds on the engine besides the one from the
battery.   Can't remember what your car is.  

I use dielectric grease on all the engine compartment connectors after a
thorough cleaning with at least an electronics cleaning agent if not
physical cleaning with scrapers/files/abraisive papers, etc.  It helps seal
out moisture that causes corrosion.  And it doesn't hinder connectivity.
