Venkata, According to "
Fuel injector symptoms for bad, faulty, dirty, clogged, or leaking injectors are :

  • Starting issues

  • Poor idle

  • Failed emissions

  • Poor Performance

  • Engine does not reach full RPM

  • Increased fuel consumption

  • Rough engine performance

  • Surging and bucking under various throttle loads

  • Smoke from the tail pipe

  • Engine Knock or Detonation which can lead to catastrophic engine failure

  • Pollution"

Venakta: I have had very good luck with a fuel injector cleaner sold by Advanced Auto called KX44 but some people like Seafoam. It is a cheaper place to start than with a mechanic.

SOURCE: 2005 F250 6.0 hard/no start.

Check the connections under the FICM. (fuel injection control module) It is on top of the left valve cover. It is the big silver flat box. There is 3 connectors underneath that should be "clicked" onto the module. Do this with the key off as there is a very high voltage there.

SOURCE: Just replaced my dirty fuel

well if the fuel filter was plugged it has already caused damage to the fuel pump, first thing you need to do is check to see how much pressure is getting to the fuel rail, then check the volume, if this is all ok then you may have a dirty injector... if not look at your pump itself.

Good Luck

A bad coolant temp sensor for the ECM will cause that problem ... they are cheap and easy to replace. One other possibility is a piece of carbon stuck in the EGR causing an internal vacuum leak ..
Good luck.

I am using accent CRDI 2005 model, and I find the black smoke coming from the exhaust and vehicle is taking pickup. when i asked the mechanic, they were asked to change the turbo which is not opening......

Black smoke indicates mild excess fuel conditions exist or inefficient combustion resulting in lots of carbon particles in the exhaust gas. This amounts to there being too much fuel for the amount of air or the fuel being injected at the wrong pressure or with a bad spray pattern.

The problem could be anything from a strangled intake to bad fuel injectors and lots of stuff in between. Generally there will be other symptoms as well as the smoke, such as poor performance and increased fuel consumption.

Beginning with a thorough underbonnet visual inspection and followed with a code read might provide a clue. Although the symptoms could be caused by something as simple as a displaced or split vacuum line to the turbo wastegate servo, it is as well to follow best practice and make certain the routine maintenance is up to date and correctly carried out before moving on to checking the correct turbo operation and pressures and egr system operation.

No one could tell you exactly what the problem is without first going through a diagnostic process. A turbo is too expensive to change unnecessarily which makes the systematic approach very desirable..

I would check the computer data for the engine coolant temperature sensor before starting it in the morning. If the sensor is not reading the correct temperature, it could cause the symptoms you are describing.

My Hyundai Matrix with CRDI engine is spewing white smoke. Mechanic says it is due to a oil leaking from an overused bearing of the turbo. He also says it cannot be repaired and has to be replaced...

It's true that turbos can't be rebuilt by the average mechanic. There is a lot of close tolerances and special tools required to repair a turbo. They have to be sent to a shop that specializes in that. I'm sorry for the bad news but thats it. Hope this helps.
