No compression
wow, no data..... all that work and no data.
data is king.
did you do it WOT wide open throttle or near?
if not its all just a waste of time.
the engine can not compress with no air supply , not at all.
so what were the WOT readings
on all 6 cylinders.
0
60
160 PSI , what?
the numbers count big times,
here is a great set of setup tests, as is the manual that came with your tool, did you read it first>/???
i use a remote start button (dirt cheap so there is no spark
or fuel , during the tests.
my guess is you skipped step 8
