Default Compression test

When doing a compression test is it OK to just unplug the coils?

Yup. Unplug the coil primary side and the injectors...and remove all spark plugs for more accurate results.

Oops, forgot abut the injectors. Getting the $%^& boots off is the hardest part. Anyone got a quick solution for that?

Be sure to use a little dielectric grease when you put them back on. It will make next time a lot more fun.

Well, compression test done...150# on all. Pulled the fuses to the ECU, injectors and fuel pump made that easier than disconnecting the injectors. Hardest part was getting the plug wires off. Doc says they should scab over and start to heal in a week or two.
