Will not turn over

Can you hear the fuel pump run for a few seconds after you first turn the key to run, before you turn the key to start?
Also, do the check engine light and security light both come on for bulb check then go out after fifteen seconds or so, or do either stay on or flash?
If the security key flashes or is on, try a spare key or clean that key where the pellet is and try again.
If the fuel pump does not run, check the fuel pump relay and PCM fuses and if okay, try to swap that fuel pump relay with something not important like a horn relay, etc, and try again if the fuel pump runs.
If there is a check engine light staying on or flashing, then there is a code set so you should have them codes retrieved.
