You car's engine needs three things to run...Fuel...Oxygen...Spark. Your engine is not getting one or all of these things, and therefore will not start. Of course you may be getting your engine may be getting some fuel, a little oxygen, and weak spark, and still will not run. Have a mechanic look at your car, could be something simple as a blocked fuel filter. Don't panic, but have a reputable mechanic check things. Hope this helps.
Does it have fuel, spark, compression?
a lot of factors to consider... will the engine rotate at all?

Start the engine up. The engine will rotate the pulley on the alternator and charge the battery.
When you attempt to start engine, nothing happens-- similar to weak or dead battery. You may hear "click" and lights may dim, but engine will not rotate
Grab the key you inserted and turned to start it and rotate it back toward you, the engine will stop.
A conventional Ford marine engine will rotate clockwise for the front end
Yes, a loose distributor can rotate so that the ignition timing for the engine is lost.
When the engine can no longer rotate.
Yes it would, but the engine will still rotate but just will not start
I took it to a shop. It was the crankshaft position sensor.
If the engine does not start: (1) rotate the carburetor main jet needle valve clockwise (close) until it touches its stopping point - DO NOT FORCE OR GO BEYOND THE POINT OF TOUCHING as it may damage the tip. (2) Rotate the needle valve counter-clockwise (open) 1-1/4 to 1-1/2 turns - this should be close enough to start the engine. Start the engine and let it warm up about five minutes. (3) Rotate the needle valve clockwise (close) slowly until the engine starts to stall for lack of fuel, then rotate the needle valve counter-clockwise (open) slowly until the engine starts to stall from flooding (too much fuel). (4) Set the needle valve to a midpoint between the two extremes for the best "purr" of the engine. If the engine "sputters" when a load is added, open the needle valve an extra 1/8 turn for a slightly richer mixture. If the engine starts and you just want to adjust the carburetor, step (1) is not necessary.
