Duramax Diesel Fuel Pump Flow and Diesel Fuel Injection Cycle

                                              Duramax Diesel Fuel Pump Injection Cycle
Duramax Fuel Flow Diagram 


Diesel Fuel Tank 
Titan Fuel Tanks
This is a aftermarket fuel tank by Titan Fuel Tanks 
Fuel is drawn by the fuel injection pump from the fuel tank to the engine through the fuel supply lines. 


Duramax Engine 
Duramax Engine and Fuel Filter Location  
Fuel flows to the fuel filter heater element housing, which combines a water separator, a prime pump, fuel heater element and a filter element.

Duramax Fuel Pumps

A mechanical Cp3 fuel injection pump at the front of the engine valley includes the fuel supply pump and the high-pressure pump.



Duramax Cp3 Bag of Parts 
.Fuel Injection Parts 
The small section of the fuel pump assembly is the supply pump called The Bag of Parts modified by Industrial Injection which creates a vacuum to pull fuel from the fuel tank to the high-pressure pump the vacuum varies with engine load and speed as the engine turners.



Duramax Fuel Injectors 
LB7/LLY/LBZ/LMM/LML Duramax Fuel Injectors 
The small section of the fuel pump assembly is the supply pump called The Bag of Parts modified by Industrial Injection which creates a vacuum to pull fuel from the fuel tank to the high-pressure pump the vacuum varies with engine load and speed as the engine turners.

The fuel rail pressure sensor is mounted in the end of the right fuel rail. Fuel is used to cool and lubricate the fuel injectors and fuel injection pump. Then the fuel return system is designed to return this fuel to the fuel tank. If the high side fuel pressure becomes excessive, then the fuel rail pressure relief valve releases the fuel into the fuel return system. The return fuel travels through the fuel cooler and then to the titan fuel tank.and does repeating the cycle of Diesel Fuel Injection System

Duramax 6.6L Valve Lash Adjustment

Duramax 6.6L Valve Adjustment  Duramax Diesel Pickup Truck This is one method used to set the valve lash on your duramax engine Valve adjustment should be performed anytime the heads are removed. It's also good practice to adjust valves during service that require valve cover remove.  TDC (Top Dead Center) First start with, locating the timing mark on the front engine cover and the harmonic balance.  Rotate the crankshaft in order to bring the number 1 cylinder to TDC (Top Dead Center) of the exhaust stroke. This mark should be aligned with the mark on the engine.  To adjust the valves, start by loosening all the jam nuts with a 14mm wrench, you will also need a flat screwdriver to make the adjustments. Adjust the valve using a .012" feeler gauge Use your .012” feeler gauge between the rocker arm and the valve bridge as pictured. The correct setting is had when there is slight resistance when moving the feeler gauge. It should not...

Duramax Glow Plugs Operation Glow Plug Relay

                                                    Cold Weather Starts and Glow Plugs  Glow Plug System Description Duramax diesel engine, air alone is compressed in the cylinder. Then, after the air has been compressed, a charge of fuel is sprayed into the cylinder and ignition occurs, due to the heat of compression. Eight glow plugs are used as an aid to starting. The glow plug initial ON time will vary based on the system voltage and temperature. Lower temperatures cause longer ON times all the times. The ECM provides glow plug operation after starting a cold engine. This post-start operation is initiated when the ignition switch  is returned to Run, from the Start position. This operation helps clean up excessive white smoke or poor idle quality after starting. Control of the instant start system, glow plugs is determine...

Duramax Diesel Allison Transmission Fast Learn Procedure

Duramax Equipped With a Allison Transmission Fast Learn Procedure   Initial Test Automatic 5 or 6 Speed Transmission  In general, Fast Learn is a procedure for Allison 1000 Series transmissions in which a series of tests are run to allow the transmission control module TCM to learn individual Clutch characteristics. Once the clutch data is learned, Fast Learn translates it to the adaptive data cells, which the TCM uses for clutch control during range shifts. Fast Learn is used at GM plants, and allows the vehicle to be driven out of the assembly plant in a near fully adapted state to minimize any customer shift concerns. The scan tool version of Fast Learn is intended to provide the same benefit following transmission repair or replacement at your local shop or Diesel Transmissions Performance Specialist .                                    BD Diesel Power Or...
