In the engine fuse box, there is also a 30amp FP fuse in there that you can pull instead of the relay.
But not really needed.
If you press the gas pedal to the floor before cranking the engine over with starter motor then fuel injectors will be OFF.
Fuel injected engines have a Clear Flooded Engine routine
Holding gas pedal down to the floor with key on engine off will start that routine, releasing gas pedal will restart the injectors, even while still cranking engine.
Try it
You should get a No Start with gas pedal down all the way.
And when doing a compression test you also WANT throttle plate open all the way, so win-win
Compression test must be done with all spark plugs removed, or crank speed will be slow and results lower
Don't need to unplug distributor if spark plugs are out
Yes just push gas pedal down will cranbking
