Hard Start After “Hot Soak”

SYMPTOM

Excessive cranking is needed to start the engine after the car is driven and then parked (with the engine off) for about 15 to 20 minutes. The engine stalls a few times before it begins to run smoothly, and the MIL may come on with a misfire DTC stored in the PCM.

PROBABLE CAUSE

In certain areas where the climate is very cold during the winter season, oil companies sell fuel that is specially formulated for improved cold weather driveability. If the weather is unseasonably warm in these areas during the winter season, the lower boiling point of this fuel causes the fuel in the lines to vaporize, resulting in a hard start or a misfire at start-up.

NOTE: This condition occurs primarily in New York, Pennsylvania, Ohio, Indiana, Illinois, Minnesota, and Colorado. If you are not located in the states listed above, contact your DSM before doing any of the following repairs. Otherwise, your claim may be debited.

CORRECTIVE ACTION

Replace the fuel pressure regulator and the PCM.
