Had a rattling noise on left side of car and car sluggish. Had mobile mechanic out did diagnostics said number 4 injector gone. Replaced it with recondition one I'm 66 and widow so don't know about this. Charged me $200.00 for injector 3 hours on job and then engine light on never been on took light off and took for run. I do do short trips and it's diesel so my son takes it down motorway. Said car was done then went to use wouldn't start and engine light on had breakdown out said lote of smoke and wouldn't start. Said injector gone it maybe not done right having a bad problem with mechanic and now saying glow plugs turbo all sorts and says he's now gone away to look it up. Have already paid for job paid $200.00 for reconditioned injector which been told was too much. Would be glad of any advise. Do I walkway and take to garage which can't afford? Thank you.

It is unlikely that the injector was installed incorrectly if the vehicle started and drove. However, that doesn't mean that the injector that was used was not faulty.

I would suggest starting with getting the current codes and going from there.

If it were me, I would ask that the mechanic that looked at it, come back and diagnosis it again. If he already did and is now telling you that it needs glow plugs and a turbo then it sounds like he is guessing.

The glow plugs are there only to warm the combustion chamber to help the fuel ignite when it is compressed. However, they are not required unless it is cold. So if it is cold right now and the engine is not starting then it could be the glow plugs.

However, let's test that by turning the key to on position and not start the engine. Let it sit there for a minute then turn the key off and back to the on position. This will allow the glow plugs to heat the chamber and then try to start the engine.

Let us know what codes are now and what happens with trying to start this way and we can go from there. Thanks

Mechanics been back and been blaming it on the glow plugs. Apparently isn't showing its the injector hard to start then runs not to bad but then after a while start it again hard to start lots of smoke and rattles a bit. But now says he's having to order sensor. So that's as far as I have got. Thank you for your messages.

You are welcome. If the engine starts but has a hard time trying to start then it could be a glow plug. However, once it starts running the glow plugs do not do anything so if it is smoking then there is another issue. Did he say what sensor?

This sounds like a possible fuel issue. It may not be a pressure issue but more of fuel contamination issue. When you have foreign material in the fuel such as dirt or even some minerals from a dirty fuel station tank, it causes the injectors to stick and cause all sorts of issues.

However, now that they have put all these parts on it, what exactly is it doing now? Is it starting and running poorly or is there something else?
