That would work too, just 6 plugs instead of 1 relay though
I just start the car and pull the fuel pump relay, wait for it to stall, then do the comp test.

Sorry, but I would disagree with this method... injectors use the flow of fuel to cool them, and they suffer badly from running when dry, which is why it is vital that you prime the fuel system of an EFI car after its been drained (rebuild etc).
