TL Will not Idle
Hey I am new to this site, but need help. I have a 2003 tl-s, went out this morning to go to work tried to crank the car. I will crank just fine but will not idle. As soon as it cuts off i can turn the key and it will start right back up but immediately cut off. any help would be greatly appreciated

Cranks over....but no start !
Have you been having any previous problems with starting or idling after start-up ? How many miles and has any work been done recently on the car ? Does the immobilizer light..."green key" symbol stay on and flash ? Do you have a yellow "CEL" warning light on ? The more info that you can give us....the better we will be able to assist you !
Things to look at if you know that the battery is good, check for blown fuses and faulty relays. The first one to inspect would be the PGM-FI, the main fuel relay. Have someone turn the key on while you listen at the opened fuel filler cap for the fuel pump to activate with a "whirring sound" for a few seconds to pressurize the system. There could be a restricted fuel filter sock not permitting enough flow pressure.
Try another different key, as maybe the immobilizer or programming is acting up. Also wiggle the key....turn it upside down, etc. as it may be in the ignition switch. Make sure that the brake pedal switch and the neutral safety switch are working. Try both "Park" and then "Neutral" when trying to start. There may be a faulty interlock or ground.
