Well it was getting gas and getting spark.
But I do not understand how it's possible: 0 psi on all cylinders ???
Even if the rings were fried, adding oil would get some small amount, no?
There is some back pressure puffing out of the air box.
I'm not sure how I could have tested compression improperly?
PO said car stalled at light and never would start again.
Timing belt is intact, can see intake cam rotate, can see both cam pulleys turn.
Very weird: intake cam pulley has some lateral wobble, can be moved by hand.
Could the exhaust pulley have come disconnected from the cam?
How would the intake cam pulley become so loose?
I have more questions now than when I started diagnosis.
