Question about Hyundai Accent

1.5 diesel. Blue smoke, not using any engine oil, no lack of power, seems to be slightly heavy on diesel. Had 2 new injectors and high pressure pump fitted under warranty but now out of warranty. Smoke seems to clear after 2 miles.

Not sure what you mean by "heavy on diesel".   Most diesels, except for late models say 2005 or newer, will have a tiny amount of smoke when cold.  It's hard for a cold motor to combust diesel without a little smoke.  
My money would be on one or both of the other two injectors, dirty, dripping or bad spray pattern.  If you near anything lke a small city, you may be able to find a shop that has the abilty to clean and check them. I use a big marine diesel shop, RPM, in Ft Lauderdale, they can generally get injectors back to new for cheap (maybe $30 each) and have a big expensive high tech machine to test them (they can afford to, they use them for engines on million dollar yachts, among others).  The hyundai injectors might be cheap, the Bosch ones are not.
Injector cleaner in a can that the parts store is happy to sell you, has not worked for anyone I know.   
If you ever lay the car up (e.g. go away on holiday for a month so) put additive in the diesel to keep bacteria from growing in it.  If you can't get it in the auto store, try a marine store.

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.

Why is there smoke in my 1999 2.5tdi nissan kingcab pickup d22 changed filters oil heavy on diesel low on power more smoke on acceleration I think it might be a bad injector any ideas would be great


injectors
faulty turbo or internal crack
low cylinder compression
valve leakage
egr valve blocked or blanked off


also check ..
fuel pump pressure fuel filter
if hard starting cold ..glow plugs

How much injector oil pressure should I have with just starter spinning over no crank and pours white smoke out exhaust


Here's you some info from a ford manual.
you can use any scan tool that will rear ICP pressure and RPM. you need at least 100 RPM while cranking.

Check oil level and quality first. if its low, it may not start, if it's old it may aerate easily(mix with air easily)

If the smoke is white/gray and smells like raw diesel, you possibly have a stuck open/Leaking Injector, Leaking injector O-Ring Seal. A failed glow plug system, can make white smoke as I am unsure of the cranking temp. if it is Blue/White there may be a compression ring issue.

A note on 7.3L injectors!!!! ALL of the Injectors are the same EXCEPT #8 (Last one on the Driver's side) It is a "Cackle" Injector. It looks the same but is slightly different. It even has a different part number in our Ford Catalog.

I hope that helps you let me know if you need anymore info.

Tools Required:
New Generation Star (NGS) Tester 007-00500 or equivalent

9c. Monitor ICP While Cranking (min 500 psi @100 RPM)
Purpose:
To determine if the injection control system can supply enough injection control pressure to sustain starting.
much-injector-oil-pressure-just-starter-ccu5ej1tcfbj3pe04s4es3xr-4-0.gif


Recommended Procedure:
Install NGS Tester. Access ICP and IPR PIDs on NGS Tester, and monitor PID readings while cranking the engine.
Note: CMP signal is required before IPR is commanded above 14%.
If ICP does not meet the minimum specification of 3450 kPa (500 psi), the injectors will not be enabled by the PCM because of insufficient rail pressure.
If IPR goes above 14%, ICP pressure should easily go above 3.4 MPa (500 psi) provided that the oil reservoir is full, the IPR valve is not stuck open, the high pressure pump is building pressure and there is not an injection control pressure leak between the high pressure pump and all of the injectors.
Possible Causes:
  • Injection control pressure system leak
  • Oil reservoir level low
  • IPR failure (sticking open)
  • Faulty high pressure pump
  • Injector O-ring leaking

My 1989 ford f250 7.3 diesel runs good up to 2000 rpms at which time it starts bogging down and throwing white smoke out can you tell me if this is a fuel injection problem?


Injectors would likely have an effect on the engine's running across the spectrum. The white smoke is unburned fuel. You could have a problem with the Injector Control Module but it sounds almost like a lack of compression.

2006 ford f350 deisel turns over wont start unless i use starting fluid it then runs great. changed fuel filter oil filter and oil, wrench symbol came on went into engine fail safe mode, said something...


the diesel engine is a 6.0L or a 6.4L? because the 6.0L don't use electronic throttle control. they control the demand of diesel threw the high pressure oil system they have a sensor call injector pressure regulator. this sensor is responsible of maintain the proper pressure in the high pressure oil system so that the engine could start . i also suggest you to check if it is any leak on the high pressure oil system or if the low pressure system is delivering the pressure required for the high pressure system to work properly. to do that you most have a scan tool. also you can check the pressure of the diesel pump that its in the chassis to eliminate the high pressure oil system as the cause of your concern. if u don't have the proper gauges to check the pressure of the diesel pump you could remove the cap of the small fuel filter that is next to the oil filter remove the filter and put the ignition switch in the on position and see in the container if you have a fast or slow filling. if you encounter that the filling is too slow then your problem is with the fuel diesel pump that is on the chassis this pump is called HFCM, Horizontal Fuel Control Module

My Isuzu Bighorn 4JX1 RJM Engine stalled after fitting it with new oil pump. It can crank but is emits smoke but not run. What could be the problem? I have tried to check if the fuel pump is not working...


the engine oil pumps are in the rear of the engine(trans out) and behind flexplate /flywheel, were any of these 2 engine oil pumps touched if so the flywheel /flexplate has to be timed to crankshaft position, so you might have it in the wrong position, if your talking about the diesel lift pump (injector pump) that also supplies high pressure engine oil to injectors, after replacing this there is a learn procedure for the rail pressure control valve that is on pump. this can only be done by dealer or some one with Tech2 scanner tool.

1992 gmc sierra turbo diesel starts and idles fine until warm up


It's time for a Italian tune up!

The blue smoke can be one of two thing.

oil drop from the valve stem (from engine head to cyclinders)
or
diesel soot collect inside the exhaust system.

===
I will take a 5-10 minutes high rpm (not redline) ran on the highway.
Pay close attention to the rear view mirror and look for black diesel soot.
=== I will use Diesel Cleen or similar product to condition the fuel. (keep moisture down)
Use the recommended amount of SEAFOAM oil additive to condition the valve stem seal/rubber parts.

I can not rule out excessive blown by.
Can you get a diesel compression tester?
When was the last valve adjustment?

Please post the actual odometer on the engine and I will follow up on it.
