Can stop cranking. With compression figures that low, it will never start. Are you sure the figures are accurate? Throttle wide open when cranking up pressure? Compression has to be at least 100 psi for the spark to ignite the mixture.
If the belt broke while engine was running, and if it is an interference engine, you may have sustained some bent valves, internal damage to one or more cylinders, but not, I don't think, to all cylinders. I don't understand how you are getting such low compression on all cylinders Those figures sound like both head gaskets are failed, or the timing is way off.
Review your timing procedure and recheck compression. Something is definitely wrong. Hope you can figure it out. Good luck.

SOURCE: no compression

Dont worry to much the Millenia is a non-interference engine so the valves did not get bent. You just need to re-adjust the belt again in its proper position.

2002 Mazda Millenia S. I would like to know the timing marks and how to get the crank to TDC?

Question edited for clarity and Madza to Mazda.
Question moved to model category.

You need cylinder 1 on compression stroke with Inlet and Exhaust valves closed. With the piston at its highest point, you have TDC.

Check Your Timing It Must Be Wrong.
you would be better off buying the Haynes or Chilton repair manuals to avoid mistakes.
If Not Done Correctly This Will Result In A Very Costly Mistake.

Timing Belt 2002 Mazda 626

re-install belt, lining up the timing marks, crank to TDC #1 cylinder, cma pulleys have marks on them, line them up to the index marks as well. If you have a drive wheel in the air, you can pop the car into 5th gear (make sure it's chocked!) and rotate the wheel to turn the engine for alignment, etc. You can put a wrench/socket on the cam bolt to align it as well.
