INSTANT ENGINE FAILURE WHILE DRIVING, THE SAME AFTER FUEL PUMP REPLACEMENT. THE ''BRAIN'' DOES NOT SHOW ANY MALFUNCTION.

Posted by on

  • ilarios_ts Jul 29, 2009

    while driving the engine fails for less than second (feels like fuel stops to flow) but due to the speed (100-120 klm/h, you see the car slowing down, the instrument for the engine rounds goes down. The "brain" does not record anything. We thought it was the fuel pump. It waw replaced. It still happens. Some say that the "brain" is affected by celular and other radiation and needs upgrade. I hope I gave details. Thanks in advance

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.

P0627 on a ford ranger tdci canot find those modules and relays to check


n the event of fuel pump "A" control circuit fault, a trouble code will be stored and a service engine soon lamp will be illuminated. Some models require multiple drive cycles (as many as 8) with a failure in order for the service engine soon lamp to be illuminated and others will activate it on the initial failure. The "A" refers to more of an area of malfunction as opposed to a particular circuit or component.

Symptoms

Symptoms may include a stored trouble code, an illuminated fuel cap malfunction lamp, and possibly an illuminated service engine soon lamp. If this code is stored, and a service engine soon lamp has not yet been illuminated, the code may be shown as pending.

Common Causes

The most likely cause of this code being stored is a defective fuel pump or relay. Most fuel pump control circuits are integrated into the PCM. Other causes may include corroded, open, or shorted wiring or connectors in the CAN Bus harness, a loose control module ground strap or broken ground wire, the CAN bus may also be defective

Transit pump code p0216 how can i fix this


P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle


The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time


Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

Kia 03 Spectra fuel OBD code P0230 primary circuit failure. Relay does not pick up Fuse is good. No spark on the ignition - relay does not pick up fuse is good. What is in the primary circuit and where...


Unfortunately there are no mechanical fixes available because that trouble code indicates a malfunction somewhere in the electrical circuit for the fuel pump and that would include wiring from the battery to the pump, the fuel pump control module and the and the car's brain, the ECM. It can be a loose connection, but if one is not easily found, then the problem has to be tested with special electrical testing equipment. More information is available but I can't post an illustration of the troubleshooting for this Diagnostic Trouble Code.

There is, however, an illustration that describes that troubleshooting at this location currently:

NOT GETTING ANY GAS TO ENGINE


It's either the fuel pump or your engine control unit. Try hot wiring the pump and see if it works. If it does you need a new brain.

Shut off while driving


Before you buy a fuel pump replacement, the cause of the shut-off may be an electrical ignition system malfunction:

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.
