If you have no compression it means that there is something seriously wrong with your engine. It could be bent valves among other things. Your car is producing a small fraction of the power it should be producing.

a wet and dry compression test is the first thing i would do. the dry can give you a starting point. if the wet test has more than a 10 psi increase, the rings are at fault.

In what exactly? Air compressor, vehicle? We can figure out a lot on here, but nobody can read minds.

That's nice. Did you want to ask a question?

In what year make and model of car or truck?

And I have no compassion.
