Stratus Coupe L4-2.4L VIN G (2003)
3. Assemble the fuel pressure measurement tools as follows.
<When using the fuel pressure gauge>
1. Rempve the union joint and bolt from special tool MD998709 (adaptor hose) and instead attach special tool MD998742 (hose adaptor) to the
adaptor hose.
2. Place a suitable O-ring or gasket on assembled special tools MD998709 and MD998742 and install the fuel pressure gauge.
3. Install the assembled fuel pressure measurement tools between the fuel rail and high-pressure fuel hose.
<When using the special tool MB991637 (fuel pressure gauge set)>
1. Remove the union joint and bolt from special tool MD998709 (adaptor hose) and instead attach special tool MD998742 (hose adaptor) to the
adaptor hose.
2. Install special tool MB991637 (fuel pressure gauge set) to assembled special tools MD998709 and MD998742 via a gasket.
3. Install the assembled fuel pressure measurement tools between the fuel rail and the high-pressure fuel hose.
CAUTION: To prevent damage to scan tool MB991502, always turn the ignition switch to the "LOCK" (OFF) position before connecting or
disconnecting scan tool MB991502.
4. Connect scan tool MB991502 to the data link connector.
5. Use the Actuator test 07 to drive the fuel pump. Check that there is no fuel leaking from any section when the fuel pump is operating.
6. Stop the fuel pump.
7. Start the engine and run at idle.
8. Measure fuel pressure while the engine is running at idle.
Standard value: Approximately 270 kPa (38 psi) at curb idle
9. Disconnect the vacuum hose from the fuel pressure regulator and measure fuel pressure with the hose end closed with your finger.
Standard value: 330 - 350 kPa (47 - 50 psi) at curb idle
10. Check to see that fuel pressure at idle does not drop even after the engine has been revved several times.
11. Revving the engine repeatedly, hold the fuel return hose lightly with your fingers to feel that fuel pressure is present in the return hose.
NOTE:If the fuel flow rate is low, there will be no fuel pressure in the return hose.
12. If any of fuel pressure measured in steps 10 to 13 is out of specification, troubleshoot and repair according to the table below.
