What happens to the PMD when you stop the engine?
After you stop the engine the fuel of course stops flowing and the water pump stops circulating coolant which in turn causes the engine temperature to actually spike for a short time. This is called heat soak. This rise in temperature heats the PMD which is bolted to the injection pump sitting on top of the engine.
