Compression test

[Timmaay]

When doing a compression test how do you disable the fuel so it doesn't spray in there while cranking the engine over? Or do I even need to worry about that?

just unplugg the fuel pump power in the rear.

do mj's have a fuel pump relay? should. if yours has a relay, you can pull it and then i always start it, and it will sometimes run for a second. when it dies you know you killed the fuel. ground the coil wire also.

Yep. Just pull the relay.

I usually just pull plug wire off the coil.

 

Been toying with the idea of installing fuel pump kill switches...

Pull the relay and run it till it dies.
