Fuel System - Engine Slow To Start
NUMBER: 14-04-00GROUP: Fuel
DATE: June 9, 2000
SUBJECT:
Vehicle Is Hard Or Slow To Start
OVERVIEW:
This bulletin involves the diagnosis and if necessary, replacement of the fuel pump module.
MODELS:
2001 (PT) PT Cruiser
NOTE:
THIS BULLETIN APPLIES TO VEHICLES BUILT PRIOR TO MAY 23, 2000 (MDH 0523XX).
SYMPTOM/CONDITION:
The vehicle is hard or slow to start. Crank times over 4 seconds. This may be due to contamination in the fuel pressure regulator inside the fuel pump. The contamination was the result of the supplier process. The new fuel pump module contains a screen internal to the pressure regulator that prohibits contamination from entering the regulator.
DIAGNOSIS:
WARNING:
THE FUEL SYSTEM IS UNDER A CONSTANT PRESSURE (EVEN WITH THE ENGINE OFF). BEFORE TESTING OR SERVICING ANY FUEL SYSTEM HOSE, FITTING OR LINE, THE FUEL SYSTEM PRESSURE MUST BE RELEASED.
Check the fuel system pressure by installing a fuel pressure gauge on the fuel rail. Start the vehicle and record the fuel pressure. Normal fuel pressure is 58 psi +1-5 psi. Turn the vehicle off and let the vehicle sit for 20 minutes. Without starting the vehicle, check the fuel pressure. If the fuel pressure has dropped below 25 psi, perform the Repair Procedure. If the fuel pressure is in the normal range (58 psi +1-5 psi), repeat the fuel pressure test. If the fuel pressure on the second test is below 25 psi, perform the Repair Procedure. If the fuel pressure is again normal, refer to the PT Cruiser Powertrain Diagnostic Manual (Publication No.81-699-99070) for further diagnosis. Do not perform this Technical Service Bulletin on a vehicle with normal fuel pressure as it will not resolve the hard or slow to start condition.
