Hi,
In most cases, a crank no-start condition is caused by either a fuel-related issue or ignition-related issue.
Here is what I need you to do. See if the engine will start if you use starting fluid. If it does and then stalls, we will know it is a fuel-related issue. If there is no change, I need you to check if there is spark to the spark plugs.
Here is a link that explains how to check for spark:

Additionally, here is a link that explains how to retrieve diagnostic trouble codes. You don't need a scanner for this vehicle. All that is needed is either a short jumper wire or a paper clip.

Try this and let me know what you find.
Take care,
Joe
