If you Cleaned up all of the Diesel There is still a Small amount of Oil from the Diesel on Anything that it Touched. Use some Spray DeGreaser on a Shop Wrag and let it dry Before you restart. Should be OK.

Astra randomly cuts out at lights and engine May be sluggish,randomly code is P0093,FUEL RAIL SENSOR?


This diagnostic trouble code (DTC) is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model.
When the computer sets this code it senses a large fuel leak in the high pressure section of the engine. The ECM in a diesel always monitors and controls the fuel pressure from the fuel injector pump to the injectors as long as the engine is running.
To set a code P0093 the ECM must sense a sudden large drop in fuel pressure within the system. This drop in fuel pressure can be internal, external or caused by a faulty sensor signal to the ECM.
When this happens, the ECM sets the code, goes into fail-safe mode which will suspend the fuel injector pump operation and allow one minute to pull over before it shuts the engine down. It will remain in fail-safe mode until the key is off.
The engine may run again but investigate the problem first. This problem will not correct itself or go away. The engine could shut down at any time or speed.
Unlike gasoline engines with fuel injection pressures of 30 to 50 PSI, diesel engine fuel pressure runs up in the Megapascal range, from 4,500 to 30,000 PSI. It takes very high fuel pressure to force fuel into the high compression cylinder of a diesel.
As you progress in diagnosing the problem be always mindful of the fuel pressure when the engine is running. It is ridiculously high! You have a code P0093 stating there is a large fuel leak in the system. Use caution when sticking your nose under the hood of a running engine with this code, or wrenching on the fuel system.
Symptoms Symptoms of a P0093 diagnostic trouble code may include:
  • Code set and malfunction indicator lamp illumination (check engine light)
  • Engine will enter fail-safe mode and shut down within one minute
  • Possible large loss of power above idle
Causes Potential causes for this DTC include:
  • Fuel injector failure
  • Fuel line common rail leak
  • Fuel pressure sensor malfunction
  • Fuel pump or lift pump failure
  • Fuel heater constantly on
  • Fuel temperature sensor failure
  • Leaks at any point in the high pressure circuit
  • Electrical connector corrosion or seating problems
  • Fuel pressure regulator malfunction
  • Fuel filter plugged dropping the fuel line volume
  • Injector pump leak
  • Fuel control actuator failure
  • Cascade overflow valve malfunction
  • Short in the electrical harness at the injectors or to the ECM
  • Fuel pressure limiting valve
  • ECM failure
Diagnostic Steps & Possible Solutions
  • Start with the engine off and doing a walkaround inspection for obvious fuel leaks between the fuel tank and the engine.
  • Lift the hood and check the oil and level. If the oil level has risen, smell the oil. If it is heavily contaminated by fuel, an injector most likely failed in the open position. Do not start the engine again until the oil and filter is changed.
  • Look under the hood for leaks. Start at the injector pump and follow the fuel lines to the fuel injector rail. Look at the injectors for signs of leaks.
  • Pull the electrical connector off the fuel pressure sensor and look for fuel in the connector. A failed sensor will allow fuel up through the sensor into the connector.
  • Check when you last changed the fuel filter. A plugged fuel filter will drop the volume enough to set the code.
  • Check all electrical connectors on the sensors and wiring harness to the injectors for missing insulation, corrosion or loose connections. If no obvious leaks have been found, go online and look up the TSBs (technical service bulletins) for your year and make vehicle. Diesels have no lack of problems as the TSBs will indicate.
Look for the code and associated repair procedures and probable causes. Chevy and Dodge reads like a book. The TSBs will include recalls on various items as well.
Look at your warranty. Most diesel engines have long warranty periods for various items. Many cover injectors for 7 years or better and 200,000 miles.
The dealer is the next step if no deficiencies are found. Checking the fuel pressure and the operation of the ECM takes special tools for a diagnosis.
Tip: Diesels outlast a normal gasoline powered engine when properly serviced. But they demand service at specific intervals to operate properly. There is no free lunch with these. Do not use any seals or gaskets that are not OEM. The pressures and temperatures call for the use of certain materials resistant to these temperatures and pressures.

2005 2KD Hiace, starts lazy,revs good when it starts but accelerator goes dead, check light comes on, then in about 2 minuets the engine dies. 093 code.


fault code is missing a letter and first number
so its P0093 large fuel leak

the fault list has list of what to check
http://www.obd-codes.com/p0093

Fuel injector failure, Fuel line common rail leak, Fuel pressure sensor malfunction
Fuel pump or lift pump failure, Fuel heater constantly on Fuel temperature sensor failure ,

Leaks at any point in the high pressure circuit Electrical connector corrosion or seating problems
Fuel pressure regulator malfunction Fuel filter plugged dropping the fuel line volume Injector pump leak
Fuel control actuator failure
Cascade overflow valve malfunction Short in the electrical harness at the injectors or to the ECM Fuel pressure limiting valve ECM failure

How to change 2002 2.8 4bj1 fuel filter


your diesel engine should have a center bolt holding fuel filter it in place.you place drain pan under fuel filter when you remove top center bolt while holding fuel filter then remove old fuel filter then take new fuel filter add few ounces clean diesel fuel in new fuel filter lubricate gasket new fuel filter cartridge then install new filter crank engine check for leaks.

I have Hyndia Tucson 2006 Deisel. I have a problem in it. This problem is smoke heavily (Black) and there is no intention of any force during press the accelerator.


mean there might be fuel leaking into the engine or the air to deisel ratio is and not atomised correctly. the main causes are normally is the air filter that isnt allowing air into the engine. Fuel filter can also be at fault not allowing enough fuel in or allowing to much in the engine sometimes. This causes the chamber to burn it out. Fuel injector if fualty could allow to much fuel or not enough. My personal suggestion would be to run fuel injector cleaner first, then change the air filter. If that doesn't fix it change the fuel filter. I would go the cheapest route first. Is is prolly something simple

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.

I have a 2001 f350 7.3. It is leaking fuel in the


Your fuel filter housing sits in the engine valley, there is a drain valve on it also has a fuel pressure regulator, may be leaking at one of these points or the hose going into the housing from the tank. Take the cover off that says POWERSTROKE on it, start the vehicle,, get a mechanics mirroer. you may be able to see where it is leaking . Hope this is helpful

1999 escort 1800 diesel not starting


For a short term solution, you could run a small electric heater within the engine compartment which will keep everything nice and warm for your early morning starts.
I remember my father using an extension trouble light and leaving it under the engine compartment during the winters.
