Rotary Fuel Pumps Timing to engine steps

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

1998 Dodge Grand Caravan Fuel Pump Relay Removal And Installation Manual

download
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.

1997 Saturn SL2 OIL PUMP REMOVAL AND INSTALLATION MANUAL

download
Removal & Disassembly Remove engine front cover. See FRONT COVER & TIMING CHAIN under REMOVAL & INSTALLATION. Using an impact driver and a T-30 Torx bit, remove and discard oil pump cover plate screws. Remove cover plate and rotors. See Fig. 11 . To remove oil pump relief valve, use a slide hammer and Relief Valve Puller Adapter (SA9103E). Inspection Replace rotors if worn or damaged. Using feeler gauge and straightedge (at cover plate), measure oil pump clearances. See OIL PUMP SPECIFICATIONS table. If clearances are not as specified, replace rotors or entire pump assembly as necessary. Reassembly & Installation Install rotors with chamfer facing away from engine. Install new relief valve (if removed). Pack pump rotors with petroleum jelly to prime pump. Install pump cover plate using new screws. Tighten screws to specification. See TORQUE SPECIFICATIONS . OIL PUMP SPECIFICATIONS NOTE: If oil pump relief valve is removed, DO NOT reuse it. Application In.

TC P1349 – VVTi ACTUATOR – EG009-03 May 19, 2003 Page 3 of 4 1. Inspect the condition of the valve cover oil baffle as per TSB EG007-02. If camshaft or camshaft position sensor damage resulting from a bent baffle is identified, repair the damage as necessary. 2. Make sure the vehicle is in “PARK” with the engine idling. 3. Referring to the screen flow below, connect the Toyota Diagnostic Tester to the vehicle and select the VVT Control Bank One Active Test (VVT CTRL B1) from the Active Test Menu. 1: DATA LIST 2: DTC INFO 3: 4: SNAPSHOT 5: SYSTEM CHECK 6: RESET MEMORY 7: MONITOR INFO 8: CHECK MODE SELECT DATA B DIAGNOSTIC MENU ENGINE A C INJ VOL A/F CONTROL CAN CTRL VSV TANK BYPASS VSV EVAP VSV (ALONE) A/C MAG CLUTCH FUEL PUMP/SPD LINE PRESS UP VVT CTRL B1 Confirm that the Vehicle is Stopped And Engine Idling 3: ACTIVE TEST PRESS [ENTER] INJECTOR 3.5ms IGN ADVANCE 11.0deg CALC LOAD 22% MAF 3.68gm/s ENGINE SPD 684rpm COOLANT TEMP186.8F INTAKE AIR 129.2F THROTTLE POS 14% CTP SW ON VEHICLE SPEED0MPH O2S B1S2 0.82V AFS B1 S1 3.25V SHORT FT #1 1.5% LONG FT #1 5.4% TOTAL FT #1 1.08 E D VVT CTRL B1 OFF INJECTOR 8.3ms IGN ADVANCE 5.0deg CALC LOAD 0% MAF 0.00gm/s ENGINE SPD 0rpm COOLANT TEMP186.8F INTAKE AIR 129.2F THROTTLE POS 14% CTP SW ON VEHICLE SPEED0MPH O2S B1S2 0.33V AFS B1 S1 3.29V SHORT FT #1 -0.1% LONG FT #1 5.4% TOTAL FT #1 1.08 VVT CTRL B1 ON 4. Using the right arrow key, toggle the VVTi actuator “ON.” 5. If at this point the vehicle does not run rough and/or stalls when the active test is performed, proceed with Repair Manual P1349 VVTi Fault Isolation Procedure (FIP). If the vehicle does stall and/or runs rough, this indicates the the VVTi control system is operating. Proceed to replace the VVTi actuator following the repair procedures listed on the Technical Information System (TIS): Engine Mechanical Section, Camshaft, Replacement The camshaft timing gear should come in the unlocked position from the factory. If it is difficult to install the camshaft timing gear, the lock pin may be engaged. To disengage the lock pin, apply and hold approximately 20 psi of air pressure at the oil feed hole located 90 degrees clockwise of the oval slot. (See Figure 1.) Once the pin has released, turn the interior assembly counterclockwise. (See black arrow in Figure 1.) B. Put the camshaft timing gear assembly and the camshaft together with the straight pin off the key groove. C. Turn the camshaft timing gear assembly (as shown in Figure 2) while pushing it lightly against the camshaft. Push further at the position where the pin fits into the groove. NOTE: Be sure not to turn the camshaft timing gear to the retard angle side (in the clockwise direction). D. Check that there is no clearance between the end of the camshaft and the camshaft timing gear. E. Tighten the camshaft bolt with the camshaft timing gear fixed. Torque: 54 Nm (551 kgfcm, 40 ftlbf) F. Check that the camshaft timing gear assembly can move to either side and is not locked
