Fuel Pressure: All Technical Service Bulletins
Fuel System - Extended Engine Cranking Time
Bulletin No.: 04-06-04-048
Date: June 30, 2004
TECHNICAL
Subject:
Extended Engine Crank Time Before Engine Starts (Replace Primary Fuel Pump)
Models:
2004 Saturn VUE Vehicles
Attention:
Technician
Condition
Some customers may comment on extended engine cranking time of 3-5 seconds before engine will start after the engine has been shut off longer than 30
seconds.
Cause
This condition may be caused by inadequate fuel pressure due to excessive fuel pressure bleed down with engine off.
Correction
Determine if fuel pressure bleed down is outside specification and, if necessary, replace primary fuel pump. Refer to service procedure in this bulletin.
Service Procedure
Caution:
Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash.
Caution:
Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline or diesel
fuel in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
1.
Install the fuel pressure gauge. Refer to "Fuel Pressure Gage Installation and Removal" procedure in the Engine Controls - 2.2L (L61) or Engine
Controls - 3.5L (L66) section of the 2004 Saturn VUE Service Manual, Vol.1.
2.
Run engine to stabilize fuel pressure and then turn engine OFF.

Complete Step 4 of "Fuel System Diagnosis" by monitoring fuel pressure for five minutes. Refer to "Fuel System Diagnosis" in the Engine
Controls - 2.2L (L61) or Engine Controls - 3.5L (L66) section of the 2004 Saturn VUE Service Manual, Vol.1.

If fuel pressure decreases by more than 100 kPa (14.5 psi) in five minutes, replace the primary fuel pump. Refer to "Fuel Tank Module
Replacement - Primary" in the Engine Controls - 2.2L (L61) or Engine Controls - 3.5L (L66) section of the 2004 Saturn VUE Service Manual,
Vol.1.

If vehicle was built up to and including VIN breakpoint 4S802436, fuel feed hose must also be replaced. Use P/N 22730899 for vehicles
with 2.2L 4-cyl. (L61) engine or P/N 22730901 for vehicles with 3.5L V-6 (L66) engine.

Saturn VUE Service Manual, Vol. 1.
-
If vehicle was built after VIN breakpoint 4S802436, the fuel feed hose does not need to be replaced.
^
If fuel pressure does not decrease by more than 100 kPa (14.5 psi) in five minutes, continue with "Fuel System Diagnosis" procedure.
