When the car died, one of the first things I checked was the relays. I tested the fuel pump relay electronically with a positive result. I felt the main relay clicking ON in place when I turned the key on, so I took that to mean that it was good.
So, today, I removed the main relay, which is a 5-prong, and tested it electronically. Again, the 87 terminal clicked ON just fine, but I got a flickering result on the 87a terminal. I bought a new main relay from the dealership, threw it in, and the car fired right up. I still can't believe it was that simple.
