Why caution should be observe during compression test?

A: You should disable the fuel pressure pump a...

You should disable the fuel pressure pump and spark of the ignition. This way you do not burn out the ignition system and flood the engine with fuel. The best way to do a compression test is to operate the starter without turning on the ignition switch. This way the fuel pump and ignition systems are not turned on. If you need some help with this, consider YourMechanic, as a certified technician can come to your home to service your vehicle.
