Construction and Road Equipment repair questions? Ask a mechanic ASAP
Thanks for asking your question. I will try and help you out.
So the engine spins over and does not start? It just blows out black smoke?
Did it just start doing this all of a sudden?
Thanks for the information.
If it is smoking and the injectors have been replaced. I would suspect a timing issue first. Has the pin timing been checked?
Ok. Yeah I would definitely check the pin timing. Let me know what you find.
Hey. I just wanted to see how things were going. Please let me know if you need more help. I am happy to assist. If my information was helpful, please leave a good or higher rating so that I receive credit. Thanks.
No problem at all.
If the pin timing is good and there are no inlet restrictions. Plus the injectors have been changed. I must next suspect a problem with the pumps in the fuel system. They can wear or become damaged and cause smoke. The o my other thing that can cause this is a problem in all six cylinders. This would be rare unless there was valve or piston damage.
Please reply back if you need more help or have more questions. I am happy to assist.
Thanks for the information. Yeah if there is no inlet restriction problem. I would next suspect the pump. Do confirm there's no cylinder problem, you may want to remove a few injectors and close the valves. Then blow air into the cylinders to make sure they hold air. If they do. I definetely suspect the fuel system.
