Preforming Compression Test, what should I know?

I've been having a bit of trouble with my 2002 sequoia SR5 RWD (posting here because there is a ton more traffic) There seems to be an issue of greatly increased oil consumption, along with puffs of white smoke coming out of my tailpipe, mainly on startup or heavy acceleration. I figured the best place to start would be a compression test, I'm using the "loner tool" program from one of the chain car parts stores, and have never done a compression test on a vehicle before. Of course I have watched a few YouTube videos, but as we all know those guys sometimes can leave out important information, especially when it comes to dealing with a specific car.

Looks like I should be able to preform the job relatively easy with these steps

1. Warm up the engine to operating temp
2. Unplug all coils from the engine (Keep these organized, they must go back to the same hole they came from!!!)
3. Unplug all spark plugs from the engine
4. Start with the first cylinder, screw the compression tester into the cylinder
5. Start the car with foot on the gas peddle, wait for 4-5 full rotations
6. Write down the compression
7. Repeat for the remaining 7 cylinders

Is there anything I should know before going in? I'm planning on unplugging the gas relay fuse(i think that's what its called?), though it looks like not everyone has gone that route. Any advice is greatly appreciated!!!

 

Disconnect the injectors, or unplug the fuel pump relay to prevent gas from washing down the cylinders and diluting your oil. The rest is spot-on.

You can do it from the engine bay with a wire jumper to connect the two copper terminals under the starter relay. Hold open the throttle body blade and touch the connections for a few seconds. Easier to keep an eye on the gauge that way.

 

Yeah I'd say this is easier than holding the throttle down while cranking. When you're ready to shut it down after warming it up just pull the fuel pump relay and let it die on its own.
