went down to autozone bought a compression tester than went home removed 15A fuse,spark plugs,intake pluged in c.tester went in my car held down the gas and turned the key over 5 times loked at the gauce through windshield nothin happend tried on #1and4 piston a few times didnt get no readings at all,yes my car is runnin good and dosent burn no oil,can anyone help please!

 

Are you sure that your doing it right? Did you screw the compression tester all the way into the spark plug hole? Maybe the guage was just broke from the store? Can you hear air coming out of the spark plug holes?

 

i blew int he gauge and it was moving [offcourse just a bit] but i was doin the test by my self well my 2 year'old daughter was there so u couldnt realy hear it while im in the car
