Chrysler Cirrus/Stratus/Sebring/Avenger/Breeze 1995-1998

Relieving Fuel System Pressure

Print

CIRRUS, STRATUS, SEBRING CONVERTIBLE AND BREEZE



2.0L and 2.4L Engines

See Figures 1 and 2


CAUTION
Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure MUST be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

  1. Disconnect the remote negative battery cable from the left strut tower. The ground cable is equipped with an insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
  2.  
  3. Remove the fuel filler cap.
  4.  
  5. Remove the cap on the fuel pressure test port on the fuel rail.

Fig. Fig. 2: Releasing the fuel system pressure with a special hose and gasoline container

  1. Place the open end of a fuel pressure release hose (special tool number C-4799-1 or equivalent) into an approved gasoline container. Connect the other end of the hose to the fuel pressure test port. Fuel pressure will bleed off through the hose, and into the gasoline container.
  2.  

2.5L Engine

See Figures 3 and 4


CAUTION
Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure MUST be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

  1. Disconnect the fuel rail electrical harness from the engine harness. This is connector C165, a black plastic connector located at the right rear of the intake manifold.

Fig. Fig. 4: Fuel rail/injector harness connector terminal identification

  1. Circuit A142 supplies voltage for the fuel injectors while the Powertrain Control Module (PCM) controls the ground for each injector. Connect a jumper wire to the terminal for Circuit A142 (terminating an 18 gauge dark green wire with an orange tracer, from the ASD relay).
  2.  
  3. Connect the other end of the jumper wire to a 12 volt power source.
  4.  
  5. Connect one end of a second jumper wire to a ground source.
  6.  
  7. Momentarily ground each of the injectors by connecting the other end of the jumper wire to the injector terminal in the harness connector. Repeat this procedure for 2 or 3 injectors.
  8.  


WARNING
Do not attempt to start the engine for several minutes to avoid hydrostatic lock.

SEBRING COUPE AND AVENGER



See Figure 5


CAUTION
Fuel injection systems remain under pressure even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

  1. Remove the fuel filler cap to release fuel tank pressure.
  2.  
  3. Remove the rear seat cushion, as described in General Information & Maintenance 0 , then remove the fuel pump access cover.
  4.  

There are two access covers underneath the seat. The panel on the far right side is for the fuel pump.

  1. At the top of the fuel pump, disengage the fuel pump harness connector.
  2.

  1. Start the vehicle and allow it to run until it stalls from lack of fuel. Turn the key to the OFF position.
  2.  
  3. Disconnect the negative battery cable, then plug in the fuel pump connector.
  4.  
  5. Install the fuel filler cap and rear seat cushion (unless other work, such as fuel pump service, requires its removal).
  6.  


CAUTION
Always wrap shop towels around a fitting that is being disconnected to absorb residual fuel in the lines.
