The vehicle developed a problem when a bolt that holds one of the injector nozzle broke leading to excessive fuel leakage from the affected nozzle.
For purpose of re-machining the bolt, the cylinder head was removed. After removing it was further discovered that only two cylinders showed signs of combustion. However, this was not given attention. Only the bolt problem was sorted out and the engine was assembled back.
Unfortunately, vehicle cant start. The engine is cannot turn. A diagnostic tool was used and it indicated there is no problem. The timing was checked and seems okay.
The mechanic concluded that it is because of the two nozzles that he suspected to be blocked. The nozzles were taken for testing and it was confirmed that two of them are blocked due to carbon accumulation.
Now my question is it correct that the reason the engine cannot fire is because full compression in the the cylinders cannot be attained with only two injector nozzles? That all four nozzles need to be working for it to start? After all, before all the problems, the engine was still running even with two injector nozzles blocked. What do you think?
