Fuel pump relay is located in the front of the trunk. Turn ignition switch to START position. If engine starts, go to next step. If engine does not start, go to FUEL PUMP RESISTOR (3.5RL) . 2. Turn engine off and ignition on. Measure voltage between ground and PCM 12-pin connector terminal No. 4 (Green wire). If battery voltage is present, go to next step. If battery voltage is not present, go to step 4). 3. Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle for at least one minute. Turn engine off. Disconnect vacuum hose No. 21 from vacuum manifold. Apply 8-12 in. Hg (27-40 kPa) vacuum to Manifold Absolute Pressure (MAP) sensor. Start engine and run at 6500 RPM with no loads and transmission in Park or Neutral. Measure voltage between ground and PCM 12-pin connector terminal No. 4 (Green wire). If less than one volt is present, fuel pump relay circuit is okay. If one volt or more is present, substitute a known good PCM, then recheck.

SMALL | MEDIUM | LARGE Previous Next Fuel Injection Pump (Distributor Type) The fuel injection pumps, Bosch® VE, Lucas CAV DPA, Stanadyne DB4, Lucas CAV DPS, and Delphi DP210, are rotary distributor pumps. These pumps perform the four basic functions of: 1. Producing the high fuel pressure required for injection 2. Metering the exact amount of fuel for each injection cycle 3. Distributing the high-pressure, metered fuel to each cylinder at the precise time 4. Varying the timing relative to engine speed. SMALL | MEDIUM | LARGE Previous Next Distributor-Type Pump Governor Balance between the governor flyweights and control lever position controls the metering of the amount of fuel to be injected. The fuel injection pump governor performance and setting can affect engine power. Special equipment and qualified personnel are required to verify governor performance. If the seals are broken on the external Bosch® VE adjustment screw, the fuel rate can, perhaps, be out of adjustment The Lucas CAV DPA/DPS fuel injection pump uses a coded spring connection to change the governor setting. Incorrect connection of the governor spring can affect performance. Adjustments and rating changes are described in the Master Repair Manual, Injector Pumps and Injectors, Manual Shutdown Levers Both fuel injection pumps are equipped with mechanical shutdown levers. These levers are spring-loaded in the run position. Not all applications will use these manual shutdown controls and there will be no cable or rod connected to the lever. NOTE: Partial actuation of the mechanical shutdown levers will affect fuel flow and engine power. SMALL | MEDIUM | LARGE Previous Next Advance Timing Mechanism Regulated pressure produced by a vane supply pump in both fuel injection pumps is used to advance the timing as the engine speed increases. A return spring is used to retard the timing as the engine speed is reduced. If a spring breaks, the timing will go to the advance position, resulting in torque loss, fuel knock, and possible engine overheating. Retarded (late) timing will result in torque loss, high fuel consumption, and white to black smoke. SMALL | MEDIUM | LARGE Previous Next The Lucas CAV DPA/DPS advance timing mechanism uses a check ball in the circuit which, if omitted during assembly, will result in no timing advance. If the fuel injection pump has been replaced or the mechanism has been removed to fix a leak, the problem can be that the check ball is missing

Fuel Pump Relay 1. Remove fuel pump relay from power distribution center at driver’s side front corner of engine compartment, near the battery. Note terminal identification on fuel pump relay. See Fig. 6 . 2. To check fuel pump relay resistance, use ohmmeter and check resistance between terminals No. 85 and 86 on fuel pump relay. Replace fuel pump relay if resistance is not 70-80 ohms. 3. To check fuel pump relay operation, connect ohmmeter between terminals No. 30 and 87A on fuel pump relay. See Fig. 6 . Ohmmeter should indicate continuity between terminals No. 30 and 87A on fuel pump relay. 4. Connect ohmmeter between terminals No. 30 and 87 on fuel pump relay. See Fig. 6 . Ohmmeter should indicate no continuity between terminals No. 30 and 87 on fuel pump relay. 5. Connect 16-gauge jumper wire between negative battery terminal and terminal No. 85 on fuel pump relay. Connect 16-gauge jumper wire between positive battery terminal and terminal No. 86 on fuel pump relay. 6. Fuel pump relay should now be energized. No continuity should now exist between terminals No. 30 and 87A on fuel pump relay. Continuity should now exist between terminals No. 30 and 87 on fuel pump relay. Disconnect jumper wires. Replace fuel pump relay if defective. 7. If fuel pump relay or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See appropriate G – TESTS W/CODES article. Fig. 6: Identifying ASD Relay & Fuel Pump Relay Terminals Courtesy of CHRYSLER CORP.

REPAIR PROCEDURE 1. Drain and refill the rear differential with Dual Pump Fluid. 2. Check the tires for proper inflation (recommended cold inflation front and rear is 26 psi) and any variation in tire size or type. 3. Test-drive the vehicle in a parking lot. Make tight, low-speed turns. If the noise is eliminated, return the vehicle to the customer. If the noise is still present, go to step 4. 4. Remove the rear differential assembly (see page 15-16 of the 1997-01 CR-V Service Manual). 5. Remove the torque control differential case, then remove and discard the 30 mm shim and the clutch assembly (see steps 1 thru 10 on pages 15-20 thru 15-22 of the service manual). 6. Remove the thrust needle bearing, the oil pump driveshaft, and the oil pump body assembly (see steps 11 and 12 on page 15-22 of the service manual). 7. Install the new flow collar over the drive pinion shaft. Make sure the tabs of the flow collar align with the oil pump pin. 8. For 1997 models: Assemble the new oil pump (spring, O-rings, piston, and pump body assembly). 9. Align the rear oil pump grooves with the oil pump pin and the flow collar tabs, then install the oil pump body assembly on the differential carrier. 10. Tighten the oil pump body assembly bolts to 12 N·m (8.7 lb-ft). 11. Align the oil pump driveshaft tabs with the grooves of the front oil pump in the oil pump body assembly, then install the oil pump driveshaft. 12. Install the thrust needle bearing with the outer race facing up.

Check engine light on and fault codes stored. Vehicle running normally. Tests/Procedures: 1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible. 4. Check valve on front right of cylinder head can be supplied with vacuum and visually checked for opening of valve. 5. Vacuum line from check valve to operating solenoid should also be inspected for cracks or being disconnected. Vacuum line follows right side of cylinder head to back of cylinder head to the secondary air solenoid located under left rear side of intake manifold. 6. The solenoid should allow vacuum flow to the check valve during vacuum pump operation. The solenoid is controlled directly by the engine control module and receives power during key-on-engine-off. Potential Causes: A.I.R. Check Valve Engine Control Module (ECM) Codes — Engine control module fault. Defective Secondary Air Pump Secondary Air Pump Relay Secondary Air Supply Hose Broken Vacuum Line
