You need these three to fire the engine up. It is unlikely you lose compression all of a sudden so focus on the first two.
Does tach bounce when you crank the engine? If tach doesn't bounce, the engine computer is not getting the signal from the crank. Fuel will be withheld. Spark will not fly either.
Is there fuel in the tank? There is a simple procedure to test the fuel pump. Jumper fuse 14 (fuel pump) to fuse 22 (hazard switch) without the key in ignition. The fuel pump should whine in the trunk area. But make sure you have fuel in the tank. Without it the fuel pump won't run even if it is good.
Your battery must be getting very weak from all the cranking. Trickle charge it and start diagnosing from the beginning with a fully charged battery.
