(VP44 style pump, with manual transmission) Vehicle Symptoms Cruising in 3rd or 4th gear a surge will occur with no D.T.C. (Diagnostic Trouble Code) It can occur in all gears but problem is mostly seen in 3rd and 4th gear. Vehicle: Nissan Patrol 3.0L with ZD30 direct injection engine Nissan Navara 3.0L with ZD30 direct injection engine Date code: 2000-2006 (with VP44 style pump) Description The vehicle will surge or intermittently go into limp home mode when driving in either 3rd or 4th gear. The neutral position sensor briefly loses the position of the gear and the ECU (thinking the vehicle is in neutral) reduces fuel quantity. With the ECU constantly changing fuelling as it responds to the vehicle being in gear then in neutral then back into gear it results in a surge condition. To simulate this problem, take the vehicle on a test drive. When the vehicle begins to surge move the gear stick laterally and hold it in place. If the surge goes away while holding the gear stick in position and begins surging again after you release the gear stick it indicates that the neutral position sensor is faulty. Solution: Replace Neutral Position switch on vehicle
PRESSURE BOX OR POWER MODULE? If you are looking for a quality product to increase your vehicle’s efficiency, power and torque, that has been tried, tested and sold worldwide – then there is only one. STEINBAUER. Quite simply there is no substitute for quality. Features include: tested & sold worldwide, operating in all climates & conditions robust construction, dust, moisture and vibration resistant quality European engineering and components easy installation no increase in rail pressure backed by a worldwide support network One major feature the power module has over all others is an in built safety feature which stops any undue stress or damage to the engine should the vehicle be put under full load for a sustained period of time. The module will cut the fuel back 1% per 1 second until it reaches a deemed safety net and it maintains this decreased power percentage until throttle is released. The module clears itself and goes back to functioning as per normal. Major benefits and features that are exclusive to the Steinbauer Power module that other chips on the market do not offer: Plug and play: a bridging harness is supplied connecting module to vehicle. No cutting wires, easy to take back to standard factory set up. Plugs into each injector (common rail) or plugs direct into the injector pump and not the ECU Does not alter the ECU, injection timing or change fuel pressures Includes a potentiometer to increase / decrease power Can include a switch on your dash to turn the module on and off as needed. Safety feature to cut fuel back on full load, stopping undue stress on the engine. There are many products on the market today that claim to increase power and torque. Buzz words like chip tuning, chipping or flashing are technologies of the past. These are products that increase rail pressure and are simplistic technology – increasing rail pressure can cause major engine failure. Increasing rail pressure can cause problems with your vehicle as it is putting higher pressure and volume through the pump and injectors, which in turn can cause premature wear to the fuel system. The increased fuel pressure can also potentially cause your vehicle to go into limp home mode as a result of the ECU detecting pressure fluctuations or higher than normal fuel pressure. The Steinbauer power module modifies the injection system by fine tuning the duration of the injectors. This is achieved by blue printing the original characteristics and intercepting the electronic signals from the ECU to the injection system. The fuel injection and engine speed are recorded and recalculated to optimise performance. The module lengthens the injection pulse width, altering the fuel map based on the engine conditions and engine speeds. It does not alter the ECU, change injection timing or alter fuel pressures.

Timing a VE Style Fuel Pump The following instructions are compiled from the YouTube Video below instructing on how to time a VE style fuel pump. Topics Covered Introduction of Scott Wood – Director at Denco Diesel + Turbo Safety Checks and Degree of Difficulty Introduction of VE Style Pump and Vehicle Pump Variations – Explanation of TDC, ATDC, BTDC, ACSD Tools Required Specific Timing Specifications for common vehicles Installing the Dial Gauge and Timing Bracket DISCLAIMER: If you are to adjust the timing on a vehicle’s pump you are doing so at your own risk. Denco Diesel and Turbo take no responsibility for your actions and suggest that you take all necessary safety precautions to ensure the safety of yourself , those around you and the vehicle. Denco Staff Member: Scott Wood Introducing Scott Wood, National Service Manager and Director at Denco Diesel and Turbo Scott has over 25 years experience in diesel fuel injection and is a factory trained technician as well as one of the directors of Denco Diesel and Turbo. Vehicle Safety Checks General Safety checks should be carried out prior to attempting to time a vehicle. Safety checks such as: Ensuring the vehicle has been turned off The vehicle has been secured with chocks Keys are removed from the ignition and that the vehicle is in neutral with the handbrake on. Introduction of VE Style Fuel Pumps VE Style Fuel pumps are commonly fitted to the following vehicles (pre common rail): Ford Courier Mitsubishi Triton Toyota Hilux Toyota Landcruiser Nissan Patrol Early Nissan Navara Mazda Bravo Pictured Below: Fuel Pump to suit Toyota HZ Landcruiser Pump variations Within your manufacturers manual you will find specific timing specifications for your vehicle. We also list common timing specifications below. Depending on the variation of your pump, your specifications will be given for TDC, ATDC and BTDC. TDC = Top Dead Centre ATDC = After Top Dead Centre BTDC = Before top dead centre ACSD = Automatic Cold Start Device – Requires 8mm Spacer for timing Put a metal plate (thickness of approx. 8mm) between the cold starting lever and thermo wax plunger To release ACSD advance: Using a screwdriver, turn the cold starting lever counterclockwise approx. 20° Put a metal plate (thickness of approx. 8mm) between the cold starting lever and thermo wax plunger. Specialised Tools Required Timing Tool Bracket NOTE: Use this tool along with a dial gauge (available at any auto shop) to assist you in timing your VE Style fuel pump, Dial gauge must have minimum 5mm travel. 95095-10400 Timing Tool Bracket Available for purchase here Specific Timing Specifications Common Toyota PUMP TIMING SPECIFICATIONS Toyota Hilux L 2.2ltr 0.94-1.06mm @ TDC Toyota Hilux 2L 2.4ltr 1.06-1.22mm @ TDC Toyota Hilux 3L 2.8ltr 0.86-0.94mm @ TDC Toyota Hilux 5L 3.0ltr 0.64-0.76mm @ TDC Toyota Dyna B 0.54-0.66 with ACSD with […]
