measured resistance of relays
Okay, if the red relay is supposed to be associated with the fuel, then it is in the wrong place and the car was running fine with the black relay prior to today!! Don't know what to make of that.
Measured resistance across 85 - 86 posts of relays: 75ohms on black (defective relay?) and open (no continuity) on red relay.
Could it be that both are working but function differently?
When I only partially replace the black relay (that was running the fuel pump until today keep in mind) the fuel pump hums away when 30 and 87a are contacted. When the relay is placed completely the fuel pump stops again...
