We need to check for fuel, spark, and compression as the engine needs these three things to start. So we need to find out which one of these items we don't have. Here are some guides that will help with this in general:

To check for spark, remove the plug and hold it against the block and crank the engine to see if there is spark at the plugs.

Next if you have spark, use starter fluid in the intake and see if it starts for a second or two. If it doesn't then we need to check compression.

Let's start with this info and let me know what you find. Thanks
