Connected my remote starter to post 1 and 4 shown in the diagram above and pushed the remote starter button to do compression test but the car still would not turn over. Not sure how else to connect it so I can use my remote starter. I kind of wanted to watch the compression gauge as I turned it over 5 revs, but no luck. So I thought well I will just use the key and turn it over 5 revs then go look at the compression gauge since I already disconnected the fuel pump. But then when I turned the key to the on position I still heard this loud rumble as noted in the video below. I always thought that noise was the fuel pump noise so I was surprised to hear it when I turned the key on. Now I wonder if the fuel pump is really disengaged or if that noise is something else. I would hate to turn the car over with fuel present in doing the compression test.
