How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

My mitsubishi L2 4d56 diesel engine common rail direct injection have not start because there no spraying diesel in the nozzel tip,what is the problem of this?


the injectors arte electronically controlled so check the immobiliser. cam crank position sensors. run fault codes. I nothing shows up have an accredited diesel specialist shop check the pump as there may be a high pressure problem ( pump failure-- common in common rail diesels as they will not tolerate dirty fuel, water and some additives in the fuel)

How do i rebuild a mitsubishi l300 fuel pump


Don't sound like a fuel pump,replace fuel filter and see if it fixes.

Late starting, thick black smoke,knocking sound and less power


Hi, sounds like the cold start system has problems, like a choke on a petrol engine that hasn't shut off when the engine is hot. When you can see black smok coming out of a diesel exhaust it is unburnt fuel that you are seeing, there is a wire on the injector pump that controls the cold start on diesels, make sure it is connected to the solenoid on the pump.

4D56 After engine is hot it won't start without


Check your fuel tank, fuel pipe and hoses might have a leaky somewhere.. else your injection pump has a leaky internal high presure pump.

Have a 2007 mitsubishi L200 4D56 command rail engine that will not run. The only way I can make this engine run is to unplug the pressure sensor located on the end of the fuel rail. Even then, it will only...


In your case the pressure sensor is faulty and needs to be replaced. 1) Stores pressurized fuel (25 to 180 MPa) that has been delivered from the supply pump and distributes the fuel to each cylinder injector. A rail pressure sensor and a pressure limiter valve are adopted in the rail. 2) The rail pressure sensor (Pc sensor) detects fuel pressure in the rail and sends a signal to the engine ECU, and the pressure limiter controls the excess pressure. This ensures optimum combustion and reduces combustion noise. ---- Rail • The rail is mounted between the supply pump and the injector, and stores the high-pressure fuel. --------- Injector:-------- • This injector replaces the conventional injection nozzle, and achieves optimal injection by effecting control in accordance with signals from the engine ECU. Signals from the engine ECU determine the duration and timing in which current is applied the injector. This in turn, determines the quantity, rate and timing of the fuel that is injected from the injector. ------------ Rail Pressure Sensor (Pc Sensor) 1) The pressure sensor detects the fuel pressure of the rail, and sends a signal to the engine ECU. The sensor is made from a semiconductor that uses the Piezo resistive effect to detect changes in electrical resistance based on the pressure applied to the elemental silicon. In comparison to the old model, this sensor is compatible with high pressure. ---------- There is a service manual for how the fuel rail sensor and fuel system works.Its for mitsubishi L200 4D56.----------- Click this link for referring the service manual:--- http://technoanswers.blogspot.com/2011/06/service-manual-for-mitsubishi-l200-4d56.html ----------- This should help.thanks.Helpmech.

4d56 Pajero Turbo Diesel, blow's alot of smoke under load. Replaced airfilter and using injector additive atm. Still blows a heap of smoke.


If your car is fitted with Manifold Air Pressure sensor (MAP) check that is operating OK. Sometimes if this is as at fault it can send the wrong signal that the engine is running lean and the engine computer (ECU) in turn compensates by injecting extra fuel. The clouds of smoke are unburnt fuel so not only does it look bad but it is wasteful/costly. The fault on a MAP can evolve slowly and therefore evades the computer diagnostics check for some while before being picked up. Also on the list of things to look at are:- 1) the mass air sensor on the air filter ducting 2) the EGR exhaust gas recirculation valve (perhaps needs a thorough clean) 3) the differential pressure feedback exhaust (DFPE) sensor - lies upstream of the EGR but if faulty can combine to lead to errors in fuel injection quantities.

4d56 engine high fuel consumption


4d56 is a diesel engine, fuel, oil, air filter change definitely, regular oil change, check tyre pressure, etc all basic things u can do yourself, after all its no 40+ MPG modern diesel engine its been around for years and years and being used in courier van, pajero and delica, i have a Delica with 4D56 turbo and its loves drinking diesel like no tomorrow, run it on veggie oil like i do you wont worry too much about your fuel consumption.
