Interesting video that provides some great diagnostics for the charging system.
Once again Paul Danner simplifies even the most basic diagnosis.
Peter shows a sometimes forgotten way to check for low voltage issues. By checking the ground side for voltage drop Peter speeds up the process and shortens the diagnostic time.
The most common causes of fuel injector failure are blockages of the pintle due to heat soak, internal shorts, and water from fuel contamination. The largest contributor to fouling of the injectors is heat soak. This is an uncontrollable occurrence on all vehicles. Heat soak occurs every time the engine shuts down. The remaining fuel on the nozzle evaporates due to the increase in temperature and lack of airflow.
