Hard Start or Dies when started
When the warm weather approaches, the engine in my XYZ starts fine in the morning, but is difficult to restart after I stop to do an errand. Sometimes it starts and then dies. Do you have any suggestions? Warm¬ weather hard starts may be caused by the high ¬vapor pressure winter fuel. Spring is a period of transition not only for nature, but also for our fuel supply. In the winter, gasoline ¬makers produce gas with high ¬vapor pressure. High¬ vapor gas ignites easier when it`s cold outside. In spring, high ¬vapor ¬pressure gas is replaced with low ¬vapor¬ pressure gasoline for summer. In spring, we often experience summer¬like temperatures one day and winter temperatures the next. Cars with high vapor¬ pressure fuel may experience hard starting symptoms similar to vapor lock or flooding on those days.
To help determine whether that`s your car`s problem, keep a log of symptoms. Note each day`s weather conditions, including the temperature, humidity, cloud cover and whether it`s rainy or dry. When hard starting appears, write how far you have driven, the temperature of the engine and how the engine reacts when you turn the key to start it. When trouble strikes, note what you do to start the engine. For example, do you hold the gas pedal to the floor? Information such as this will help a technician diagnose the trouble.
If hard starts are caused by high¬ vapor ¬pressure fuel, you will have to wait until the supply runs out.
