You can use the key but since you have a remote starter, I'd say use that instead so you can see what the gauge is doing as you crank (be sure to wear safety glasses). The gauge needle should stay put. If it drops after you stop cranking, it's leaking.

The bungee on the stop lever must be strong and tight and pulling at the correct angle. I stopped using that method (because it's dangerous if the bungee let's go) and use a wooden stick to wedge the stop lever and keep the stick in my compression tester kit. I'll see if I can get a pic later.

Not sure what tools you're using for glow plug removal. For fastest results, you should be using 1/4 in drive ratchet, socket, extension on a universal on all except #4.
