That is how the security system keeps the car from starting. Is you security light on? Could be a fuse or a broken wire you will need to crack a manual, I do not remember this being a common issue.

have you tried the primer jumper wire to see if fuel pump comes on. http://shbox.com/1/fuel_pump_prime.jpg

pcm should be sending an enable signal have a look here and see if it can help. http://shbox.com/1/pass_key.jpg

You're going to need to check for voltage and a ground between the dark green/white (465 at relay term #85) and the black/white (451 at relay term #86) wires at the relay when the ignition switch is turn to the on position. This is the power supply that energizes the relay coil to close the relay contact. If the PCM contact is faulty or the dark green wire is broken between the PCM and relay coil or the black/white wire between the ground source and the relay could cause what you're describing. The attached trouble shooting chart may help with checking the system.
