I want to check the compression, how do I stop the flow of fuel to the motor as I spin it?
Thanks,
Mike

 

What year is your car?

s4 - remove the eji comp and egi inj, that'll stop fuel and spark.
On s5 just the one eji fuse will do the job

Thank you, you may laugh at the double post but the first post did not appear on the board for one hour, so I posted again thinking it went into cyberspace......
Sure are a knowledgeable bunch of helpful friends on this board. Have learned a lot.
