Chart 3

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.
