RAM 3500 Chassis Cab Truck 2WD L6-6.7L DSL Turbo (2010)
1. Perform the following to purge air from the system:
-
With the scan tool, actuate the In-Tank Fuel Lift Pump Module.
-
Open the Flow Test Valve (1) for 10 seconds, then close the Valve.
-
Turn the ignition off.
-
Disconnect, empty, and then reconnect the Reservoir Assembly (2).
2. Perform the following three times to find the average flow rate:
-
With the scan tool, actuate the In-Tank Fuel Lift Pump Module.
-
Open the Flow Test Valve (1) for 10 seconds, then close the valve.
-
Turn the ignition off.
-
Measure and record the amount of fuel in the Reservoir Assembly (2).
-
Disconnect, empty, and then reconnect the Reservoir Assembly (2).
3. Add the three recorded measurements and then divide the total by three to calculate the average flow rate. The flow rate is 500 ml in 10 seconds.
Does the average flow rate meet or exceed the specification?
Yes
-
Repair complete. Verify repair by performing the High Pressure Fuel System test procedure again.
-
Perform the POWERTRAIN VERIFICATION TEST - 6.7L. See: Powertrain Management/Computers and Control Systems/Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Powertrain Verification Test.
No
-
Use the wiring diagram as a guide to check the In-Tank Fuel Lift Pump wiring for an open, high resistance, or short to ground. If the In-Tank Fuel
Lift Pump wiring is OK, remove the fuel tank and replace the In-Tank Fuel Lift Pump Module.

Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Powertrain Verification Test.
8. IN-TANK FUEL LIFT PUMP FLOW TEST WITHOUT DECAY TESTER
NOTE: Before performing the IN-TANK FUEL LIFT PUMP FLOW test, verify that the fuel level in the fuel tank is above 1/4 full. If fuel
tank is not above 1/4 full the pump will take in air causing the test results to be inaccurate.
1. Disconnect the low pressure fuel supply line from the High Pressure Fuel Pump. Install fuel system test fitting 9863 onto the end of the low
pressure fuel supply line. Then, connect one end of a section of fuel hose to the test fitting and place the other end of the fuel hose into an empty
fuel container.
2. Turn the ignition on.
3. With the scan tool, actuate the In-Tank Fuel Lift Pump Module.
4. With the In-Tank Fuel Lift Pump Module running, place the fuel hose into a 1,000 ml graduated cylinder for 10 seconds and then return the hose
to the fuel container.
CAUTION: Stop all actuations.
5. Turn the ignition off.
6. Measure the amount of fuel in the graduated cylinder. The fuel output specification is 590 ml in 10 seconds.
Does the amount of fuel in the graduated cylinder meet or exceed the specification?
Yes - Vehicle starts and runs:
