Alright, so I'm trying to run a compression test on my motor.

I don't know if I'm just being a new guy or what but I can't get the gauge to show any readings. I'm using one that threads into the spark plug hole...

what am I doing wrong?

Heres how I have it hooked up:

Take all 4 plugs out at the same time, and hold the throttle wide open while you crank. Seems to be hooked up ok....maybe the guage is no good?

thats what I did do

I rented the tester from AutoZone and I think it was brand new because it still had a cover over the gauge face...I was thinkin maybe I did something wrong with the connection between the hose and gauge??

Where's the oring? is the shrader valve in the line?

Kodatech

No it looks correct....see that little button below the guage?...make sure it isnt stuck..and make sure it is all connected nice and tight...no leaks.

IonNinja

well everything is tight and i still get no reading?!

gonna see if i can take it back and get another one...
