However, there are a few exceptions to this rule. Some older diesel vehicles, particularly those with mechanical fuel injection pumps, can be push-started if they are in good working order and the fuel system is properly primed. To push-start a diesel vehicle, the vehicle must be in neutral gear, and the ignition key must be turned to the "On" position. The vehicle should then be pushed or towed until the engine starts.
It is important to note that push-starting a diesel vehicle can be dangerous, as the vehicle may suddenly lurch forward if the engine starts. It is also important to make sure that the parking brake is engaged and the vehicle is in neutral gear before attempting to push-start it.
Overall, it is not recommended to attempt to push-start a diesel vehicle unless you are absolutely certain that the vehicle is capable of being push-started and you are familiar with the procedure.
