When you have the no start you need to make sure the fuel pump is energizing and that you have fuel in the fuel rail with pressure. You may be having the beginning of a bad fuel pump ready to go south. Second option would to be sure when turning to start the vehicle that you have power to the ignition coil. You need gas and electric spark to start any vehicle. Without either, the vehicle will just crank.
Do you have a master key ?
With a master passkey III key (Black), turn ON the ignition, with the engine OFF.
Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
Turn OFF the ignition, and wait 5 seconds.
Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
With a scan tool, clear any DTCs.
It's the anti-theft system . (SECURITY ) Keeps vehicle from being stolen ! Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II?® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
Your best bet would be have it towed to a qualified repair shop !
Have it checked for DTC'S - diagnostic trouble code's . I suspect the problem is with the tdm module or the ignition switch ???? Assuming will only get you into trouble . If the PCM - engine computer does not see the right coded meassage from the TDM it won't turn on the fuel injectors or it will cut them off in two seconds . .

Ignition Key With Wrong Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs one of the two following actions when you attempt to start the vehicle with a wrong ignition key:
• There are 15 PASS-Key® II resistance ranges. The PASS-Key® II resistance may be one of the 14 valid but incorrect PASS-Key® II resistance ranges. The theft deterrent module will perform the following actions when you attempt to start the vehicle (if the condition is present during an engine start attempt or for 1 second any time after the engine has started):
• Turns on the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit
• The password disables fuel delivery to the engine.
• Disables the theft deterrent relay, which disables the starter circuit
• Disables sampling of the PASS-Key® II resistance for 3 minutes
• The 3 minute time period is called the shut-down period.
• Disconnecting the battery will not clear the timer sequence. The timer sequence will resume when battery power is restored.
• Inserting the proper key during the vehicle shut-down period will not start the engine. The engine will not start until the shut-down period has elapsed.
• After the shut-down period, the engine will start if the correct ignition key resistor pellet is used.
• The PASS-Key® II resistance may be correct and allow the engine to start. Later during the same ignition cycle, the PASS-Key® II resistance may be one of the 14 valid but incorrect resistance ranges. The theft deterrent module will perform the following actions:
• Enters the fail-enable mode
• Turns ON the SECURITY indicator
• Sends a password to the PCM through the fuel enable signal circuit when more attempts to start the engine occur
• The password allows the fuel enable circuit to deliver fuel to the engine.
• Enables the theft deterrent relay, which also enables the starter circuit.
Ignition Key With Correct Resistor Pellet Code is Used To Start Engine
The theft deterrent module performs the following actions when the correct ignition key is used in order to start the vehicle:
• Enables the theft deterrent relay. The theft deterrent relay enables the starter unit.
• Sends a password to the Powertrain Control Module (PCM) through the fuel enable signal circuit. As a result, the PCM allows fuel delivery to the engine.
Sound like a SECURITY SYSTEM is armed; I suggest check in the Owners Manual to disarm...
When the PASS-Key III system senses that someone is using the wrong key, it shuts down the vehicle's starter and fuel systems. The starter will not work and fuel will stop being delivered to the engine. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes.
When trying to start the vehicle if the engine does not start and the SECURITY light comes on, the key may have a damaged transponder. Turn the ignition off and try again.
If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty.
ANTI-THEFT SYSTEM Passive anti-theft system Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started.Without the use ofyour specialignition key, the vehicle will notstart.
During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.
Anti-theft system Briefly illuminates when the ignition is turned to the ON position to verify that the passive anti-theft system is operating
Also, its possisble that tou have actovated the fuel pump switch.
When you turn the ignition on, it starts the fuel pump then sends fuel to the injectors. Since there is no ignition to engage the pump, it will 'starve' the vehicle of fuel. You might run a power source directly to your fuel pump but I'm NOT suggesting that because it would be wrong for me to tell you something like that... plus it could be dangerous. Remember, if you just happen to decide to do something like that, the fuel pump will not stop until you disconnect it (or it burns up). Be Careful!. Don't forget to vote if this helped you.

there may be a fuel problem. The fuel pump may not be working properly. Also, if the vehicle has been run out of fuel, there may be air in the lines and turning the ignition off and on will turn on and off the fuel pump which could push the air bubble through the system long enough to let the vehicle run and when it is turned off the air bubble will work its way back up to cause problems again. There may be a problem with the wire from the ignition to the fuel pump as well. When it wont start, you can pop the fuel line off the fuel pump while the ignition is on, or have someone turn the engine over while the line is off and it should push fuel out. If it pushes fuel out, you may have an air bubble in the line somewhere. You can get rid of the bubble by turning the engine over and crack each injector line off one at a time while the engine is being turned over.
Hope this helps!
