When you're dealing with a no-start complaint on a gas engine, you only have three things to check. Is it getting fuel? Is it getting spark? Can the engine compress the air/fuel mix? But on a diesel, it's another story. First, there's no spark plug or ignition system to consider. Diesels are compression-ignition engines. They rely on high compression pressure to heat the air/fuel mix to the point of combustion. Cylinder pressures can rise to 500 psi or more, compared to a high of 200 psi on a gas powerplant. |
