Hi,
In most cases, a crank no start condition is the result of either a fuel-related issue or ignition related. In other words, the engine isn't getting the fuel needed to run or there is a loss of spark to the spark plugs.
It is easy to narrow down which it is. Do this. See if the engine starts if you use starting fluid. If it starts and then stalls, we know it is fuel related. If there is no change, then I need you to check for spark to the spark plugs.
Here is a link that explains how that is done:

Try this and let me know the results. Additionally, when cranking the engine, see if the tachometer is moving a little. If it doesn't move at all, we may have a faulty crankshaft position sensor.
Let me know what you find.
