Hi there, thanks for writing in. Unfortunately, if there is no compression, you have internal engine failure. This could be piston ring failure. Generally, a used engine would be the order for the repair as the cylinder walls could be damaged as well and the block would have to be replaced. If you'd like a second opinion on this, consider having a certified technician, such as one from YourMechanic, diagnose your no start condition firsthand. Best of luck.
