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

Removal All vehicles WARNING: Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury. WARNING: Fuel in the fuel system remains under high pressure even when the engine is not running. Before working on or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions may result in personal injury. 1. Disconnect the battery ground cable (14301). For additional information, refer to Section 414-01 . 2. Relieve the fuel pressure. For additional information, refer to Section 310-00A (Gasoline) or Section 310-00B (Natural Gas). 3. Disconnect the fuel lines. For additional information, refer to Section 310-00A (Gasoline) or Section 310-00B (Natural Gas). 4. Remove the throttle body (9E926). For additional information, refer to Throttle Body in this section. 5. On gasoline engines, remove the EGR valve to exhaust manifold tube (9D477). For additional information, refer to Section 303-08 . 6. Remove the drive belt (8620). For additional information, refer to Section 303-05 . Vehicles equipped with natural gas engines 7. Disconnect the fuel temperature sensor connector. 8. Disconnect the fuel pressure sensor connector. All vehicles 9. Disconnect the main fuel shut-off solenoid connector. 10. Disconnect the generator cable, electrical connector, and harness pin-type retainer. 11. Remove the bolts and the generator mounting bracket (10153). 12. Remove the bolts. 13. Unclip the accelerator cable (9A758) and the speed control actuator cable (9A825) from the two crash brackets and position out of the way. 14. Separate the LH heated oxygen sensor and the transmission electrical connector from the bracket at the rear of the cylinder head. 15. Separate the fuel charging wiring pin-type retainer from the crash bracket. 16. Remove the wiring bracket. * Disconnect the wiring connectors. * Separate the transmission harness from the stud. * Remove the nut and the bolt and remove the bracket 17. NOTE: On natural gas vehicles, there are no EGR vacuum connections. Disconnect the vacuum lines and position out of the way. 18. Remove bolt and stud and remove the crash bracket. 19. Disconnect the ground connector from the RH rear stud. 20. Disconnect generator harness locator retainer from LH front stud. 21. Disconnect the eight fuel injector electrical connectors

AIR/ FUEL RATIO MONITOR INSTALLATION INSTRUCTIONS

1. The exhaust weld bung should be welded to a 3/4-inch hole in the exhaust system located as close as practical to the exhaust manifold/header coupling flange. Your local muffler shop should be able to perform this task at a reasonable cost. Be sure to allow clearance for the sensor and its wire harness. 2. Screw the O2 sensor assembly into the weld bung using a 7/8″ wrench. A small amount of anti-seize compound is on the threads of the sensor. Should this be wiped off, we recommend reapplying anti-seize to the threads. 3. Disconnect the battery prior to any electrical work. Always disconnect the ground terminal first to reduce the possibility of shorting a wrench from the +12V side of the battery to ground. 4. Select a mounting location for the Air/Fuel Ratio Monitor display that may be viewed easily, but in reach of the supplied harness. Install the Air/Fuel display using the supplied velcro strips. 5. Locate a place in the firewall to feed the three wires through to the engine compartment. Usually there are existing through holes that may be used. A rubber grommet is provided and should be used if required. NOTE: Use care in routing wires near or around hot exhaust components. Shorting the O2 sensor signal to ground may permanently damage the sensor. 6. Insert the three-pin Weather Pack connector pins into the supplied connector body. Refer to Figure 1. 7. Route the wires to the mating connector attached to the O2 sensor and plug the cable together. NOTE: To prevent catastrophic failure of unit, avoid routing wires near spark plug wires. Be especially careful to avoid running wires parallel to plug wires. Allow even more clearance with high energy ignitions. 8. Locate and connect the Red wire to a source of +12 volt power that is on when the engine is running. 9. Connect the Black wire to the rear of a cylinder head or a manifold bolt. Make sure the bolt hole is free of paint or other nonconducting material. DO NOT USE VEHICLE SHEET METAL AS A SYSTEM GROUND. Use an Ohm meter to check resistance along the path between the ground location and the O2 sensor bung. It should read less than 1 Ohm. 10. Re-connect the battery (positive terminal first), and start the engine. 11. The Air/Fuel Ratio Monitor is now ready for use. Indications begin after the exhaust temperature reaches about 600°F (after approximately 60 seconds)

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.
