May 6, 2006
Applies To:
2004 TL - From VIN19UUA6...4A000001 thru 19UUA6...4A058862
Long Crank Time or Hard Starting
SYMPTOM
There is excessive cranking or the engine is hard to start.
PROBABLE CAUSE
There are two possible causes:
1.
Contamination in the fuel pressure regulator causes the regulator to stick or intermittently stick, which causes a delay in fuel pressure at start-up.
2.
Exhaust gas backflow into the intake manifold at engine shutdown may cause a poor mixture of intake air and fuel at the next engine start-up.
CORRECTIVE ACTION
Replace the fuel pressure regulator, if needed, and use the HDS to update the PGM-FI software in the ECM/PCM.
NOTE:
Vehicles with VIN 19UUA6...4A041208 thru 19UUA6...4A058862 already have an improved fuel pressure regulator. For these vehicles, skip
DIAGNOSIS, and go to step 10 of REPAIR PROCEDURE to update the PGM-FI software in the ECM/PCM.
