Hello,
Typically, when an engine cranks strong but does not start, is due to either not getting spark or fuel.
When you turn on the key, can you hear the fuel pump come on?
Inoperative fuel pump can be due to a bad relay, wiring or bad fuel pump. If the pump does not come on first check the relay. That relay is located in the under-hood fuse box (see diagram). Check for any corrosion or burnt pins.
This relay can also be tested:

If the relay is good, then check to see if there is power to the fuel pump harness. Power to the harness, but pump not coming on, this will likely be a bad fuel pump.
If the fuel checks out, then make sure you are getting spark to the plugs. Check for wear, inspect fort oil fouling, or carbon buildup.
