Chart 3

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2008 Mercury Sable, 2008 Mercury Mountaineer, 2008 Mercury Milan, 2008 Mercury Mariner, and 2008 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: An extended crank because of a no start may load the exhaust system with raw fuel, damaging the catalytic converter after the engine starts. For vehicles equipped with a secondary air injection (AIR) system, carry out the following after the no start concern is repaired: Disconnect the electric AIR pump relay, run the engine until the surplus fuel is used up, and connect the relay. Disconnecting the relay may set a continuous memory PCM DTC that needs to be cleared.
