I opened the relay and inspected the insides of the relay. No cracked solder however, it did have lots of grime and green stuff near the solder connecting the socket pins.

There are two relays mounted on the board, and they're the same size.

With my trusty RS Multimeter, I found these:
1. Between Pins 30 and 87, 61.8 ohms.. with the 1st relay pushed down, its 0 ohms.

2. Between pins 30 and 87V, its infinite ohms... with the 2nd relay pushed down, its .71 ohms.

Two things come to mind:
1. The green powdery stuff on the board is making funny electricity (sorry, I made that up).

2. The 2nd relay has bad contacts... note, my car started with pins 30 and 87V shorted, so this faulty component inside the Fuel Pump Relay blackbox is WHY the relay doesn't power up the fuel pump.

I also checked my German to English dictionary, and "Kaltart Steuerung" literally translates to "Cold Start Controller". So I'm guessing here that this particular box's main function is to control the Cold Start Injector --- so I deduce pins 30 and 87 activate it. And 30 and 87V is the secondary function, which powers the fuel pump.

Did I get it right?

Your inputs would be great. Thanks again!
