SOURCE: fiat doblo 1.9 diesel year 2007. engine stop when low fuel tank

There is a possibility that your fuel transfer pump has quit and fuel is getting to your engine by gravity only. Have your tranfer pump flow rate tested. Also renew your primary fuel filter.

SOURCE: 2006 VW tdi black smoke while accelerating

The only sensible way forward is to get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.
There are lots of possible reasons for the problem and guessing will not really help. If these suggestions turn out to be sound, please give my reply a "Fixya!"rating, If they do not, please hold off rating and add a comment with more details so I can try to help you further. Cheers, D

I have a opel corsa B 1.6is 2000 model it first started with cutting out when I come 2 a stoped then got worse where it didn't wana start again took out spark plugs they were pitch black sign of ova...

It is a pity that you altered the settings before you did a fault code run. It may have been a simple case of faulty HO2s/o2s sensors that affect the control of the air /fuel mixture. Did you check the condition of the injectors before doing anything. Both of these result in over fuel and black plugs.

Wont rev and smokes badly

Hi, If the car is smoking that mean something wrong your engine.
If you can not rev more to 1800 you have compression problem. May you should have broken rings.
Do your compression test first,

2004 kia carens 1.9 diesel will start up but only rev up slightly then emits black smoke

With all the reported problems with this vehicle I would start by having the fault codes read. I am sure that you will get a lot of codes that will relate to all the faults you want answers for.

Car starts but revs for a few seconds with lots of black smoke and then cuts out have disconected exhaust from manifold but no change

Is this a diesel TDI PD ?? If so i had the same problem with one of these TDI engines and traced it to the crank sensor signal implausable. The revs would start increasing with no pressure on the throttle, lots of black smoke and then cut out. The crank sensor wiring was at fault in this case. The ECU didnt know where the crank position was in relation to the camshaft and was guessing when to inject the fuel. Hence the black smoke ! Hope this is of some use.

Engine starts but does not rev up

Double check the timing marks on the crankshaft and cam pullies. I bet your off by a tooth after replacing the timing belt.

Loss of power, glow plug light on when no power black smoke

If the head has been replaced have the pump timing checked.It sounds like they have not set the fuel pump timing right for you.Yes its a possibility its the EGR valve but all you have to do with that is remove it and claen it with carb cleaner.And replace it.
