You can start by checking the basics. Check for spark while cranking. Check for fuel pressure. This will narrow down the problem to a more specific area.
If you suspect a key chip problem, you can take the VIN to a Ford dealer, and they can tell you if this vehicle uses a transponder key. If so, they can also look up the codes and cut and program a new key for you.
If you find that you only need an ordinary key, then it is back to the basics. Let me know what you find, and I can point you in a direction that will help you to solve the problem.
