Your battery has a full charge and connections all good? The diagram shows the crank relay, under hood fuse box. Because there are no terminal numbers at the crank relay in diagram, sometimes that means the relay is soldered into the fuse box and you can't pull it out. You could use a remote starter button, your local autostore probably has one. The leads on the starter button hook up to the B and S terminals at the starter motor, then just press the button, the starter motor should crank the engine, you don't need to use the key. If you try that make sure the tranny is in park or neutral and parking brake is set. Just my opinion.

Just to add, if it cranks good but won't start, it's not the starter motor relay. Maybe I misunderstood? If it cranks good but won't start, have a helper crank it while you check for spark--proper fuel pressure and fuel injector pulse. Any applicable trouble codes?
