Ok I did a comp. check but it was my first time doing one on a rotary. The gauge has a valve so when it reads pressure it stays at the highest pressure read.

I had to hold the gauge in place becaus it doesn't skrew in it has a rubber fitting



I am thinking I should go to Napa and get the one there.



Any suggestions?

 

take the schrader valve out of the compression tester and watch for 3 even bounces.

 

How do you test the compression? do you have someone turn the key while the open relay ciruit is out? And what compression testers should be used?

 

check the fsm for the CORRECT way to do it
