Compression is an engine basic function, no compression means that cylinder won't function. A bad crank sensor will not cause a loss of compression, that is an internal engine problem,ie bad valves, broken piston, etc. a no spark could be the bad crank sensor, but I believe that you have more serious problems with the engine.

do agree with tennis shoe, it can be a gasket as well, no compression is a bad thing.
