Compression Test 07 C6 A6
I have never done a compression test on a car that has the push button start. Is there a special procedure to follow? How many revolutions will it make before it stops? Any info on this is greatly appreciated.

Compression test
I have a 6 speed manual, after disconnecting the main harness to the coils on the left and right bank (this is to make sure the car will not start) I also will remove the fuel hose going to the fuel rails and cap the fuel line from the tank ( cap it good, there is close to 50 psi there).
Some people pull the fuel pump fuse. I you dont disable the fuel system the excess fuel will wash the cylinders and skew the results not to mention flood the motor. On the standard I push in the clutch and push the starter button, after 3 or 4 hits on the compression gage let up on the clutch and the starter will stop. If you have an auto hitting the button again or let up off the brake I think will stop the starter motor. Need some automatic guys to help me here.
Hope this helps

We want the key back!!!!!!!!!!!!!!!
You can get one of these so the computer isn't trying to start the car completely. You have the control, just remember the t-body blade should be open.
