    Little chance of water in the injection pump because the fuel filter will stop water to prevent such an expensive problem.

Yes damage will result if the fuel/water separator is not drained regularly. Water in fuel will cause combustion problems, corossion internally,

P.S. if there is enough water in system it will seep past the filters.

Yes, Diesel engines can tolerate a little water but alot of water (over a period of time) can damage cylinder walls, pistons, injectors, and the injection pump.

My td 27 diesel engine the engine luck on sylinder 2@and i sove it but it steel lock again on the same sylinder 2, i se the oil pumping what is the cause?


not the oil pump
most likely a leaking injector causing a hydraulic lock where the fuel sitting on top of the piston is not allowing it to go over tdc
pull all the injectors
turn it over and push the fluid out the injector holes
have the injectors professionally serviced
bad news if you get water out of the injector hole as that indicates a head gasket or cracked head allowing water into the cylinder

Idle fine, then run ok for few minutes, then cant go over 15 mph,new filter, new supply pump, suspect turbo or injector pump


Hi , you probably have water that's went from the tank to the pump. DIESEL PUMP. The worst thing that you can do is let your fuel go way down low and some water is taken in with fuel + water . The fuel pump is a mechanical pump with moving parts and you can't let water in . Certain pumps ,diesel pumps have a latch valve and you don't want water to sit for any length of time in the surrounding wall of the valve as it will rust this may cause the valve to stick then your car may go to rev excessive sometimes high revs , i mean screaming rev's. Please get the pump checked.

P38 diesel fuel injector pump overheats and inhibits starting


This is an unusual problem as injector pumps use diesel to lubricate internally and to cool the pump. For it to overheat and cause you problems means that fuel is escaping under high pressure or the operating pressure is excessive . Best discuss this with a professional diesel pump repair shop as I feel there is a serious problem in the pump.

How can water get to the diesel tank from the radiator reservoir?


there is no connection between the coolant reservoir and the diesel tank. However when running diesel fuel becomes hot from the return fuel from the injectors that is used to cool and lubricate the injectors. Diesel tanks are vented to the atmosphere and so condensation forms in the tank when it cools down. This accumulates and is picked up and goes to the filter ( should have a water separator in the system) Left untreated a moss grows in the fuel which blocks filters and injectors Use a diesel fuel conditioner to control the rubbish A method of controlling water in the tank that is used by all long distance operators is to fill to the top every time before shutting down for the night.

Noise fuel injectors


When a diesel injector goes bad and no longer sprays a fine mist of fuel but 'hose pipes', this causes engine knock or hammering. Some folks call this 'nailing' but is usually under acceleration when this 'nailing' is heard.

Injector must be bech tested at a diesel shop.

Hi, I own a 3.0 d4d toyota fortuner (same engine as 3.0 d4d hilux) and as of yesterday it started belching white smoke. it starts and idles perfectly fine, the exhaust just smells off. not like unburnt...


White smoke on diesel engines, means water in combustion chamber. Blue smoke means oil.
In what condition was the filter you removed? How bad? Temperature issues? Missing coolant maybe? If yes, you might as well have an internal leak. Some gasket maybe. Check all you vital fluids levels. If anything missing, take the time to empty the engine oil on a can, and check the colour. If it will look like chocolate brown, then you do have a leak from the inside.

Diesel wont start


1. Make sure that the battery is fully charged.

2. Check the fuse for fuse # 30. This is the fuse for the:
Fuel Heater (Diesel only),
Wastegate Solenoid (Diesel only)
Injector Driver Module Relay Coil (Diesel only)

3. It is not uncommon for the fuel bowl heater (little wire in the bottom of the fuel bowl) to go bad. If the fuse is burnt, you can pull the small plug on the back of the fuel bowl to get around a bad fuel bowl heater.
As far as fuel leaking, a common problem is the water separator valve behind the fuel bowl. There are o-rings in there that tend to go, especially now that we're burning the ulsd. Do a search on water separator, and you'll find volumes of information and how-to's to swap out the o-rings.There's other reasons that you could have a fuel leak, but that is where I would start first. And welcome to The Diesel Stop.

Hope these helps and have a great day!

WERE IS THE FUEL FILTER


A fuel filter is a filter in the fuel line that screens out dirt and rust particles from the fuel. They are normally made into cartridges containing a filter paper. They are found in most internal combustion engines.
Fuel filters serve a vital function in today's modern, tight-tolerance engine fuel systems. Unfiltered fuel may contain several kinds of contamination, for example paint chips and dirt that has been knocked into the tank while filling, or rust caused by moisture in a steel tank. If these substances are not removed before the fuel enters the system, they will cause rapid wear and failure of the fuel pump and injectors, due to the abrasive action of the particles on the high-precision components used in modern injection systems. Fuel filters also improve performance, as the fewer contaminants present in the fuel, the more efficiently it can be burnt.
Fuel filters need to be maintained at regular intervals. This is usually a case of simply disconnecting the filter from the fuel line and replacing it with a new one, although some specially designed filters can be cleaned and reused many times. If a filter is not replaced regularly it may become clogged with contaminants and cause a restriction in the fuel flow, causing an appreciable drop in engine performance as the engine struggles to draw enough fuel to continue running normally.
Some filters, especially found on diesel engines, are of a bowl-like design which collect water in the bottom (as water is more dense than diesel). The water can then be drained off by opening a valve in the bottom of the bowl and letting it run out, until the bowl contains only diesel. Many Fuel Filters contain a water sensor to signal to the ECU or directly to the driver (lamp on dashboard) if the water reach the warning level. It is especially undesirable for water to be drawn into a diesel engine fuel system, as the system relies on the diesel for lubrication of the moving parts, and if water gets into a moving part which requires constant lubrication (for example an injector valve), it will quickly cause overheating and unnecessary wear. This type of filter may also include a sensor, which will alert the operator when the filter needs to be drained. In the diesel fuel filter there is (usually) a fuel heater to avoid the paraffin (in case of lower temperature) inside the filtrating element which can stop the fuel flow to the engine.
