Why does my engine always start cold?
Cold batteries simply don’t produce the same amount of power as warm batteries, and this effect can lead to starting issues. When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. If the battery is already low on power, this can result in a non-starter.
Why does my car hesitate to start when its hot?
This problem is closely related to vapor lock. Hard warm starts can also be traced to a leaking fuel pressure regulator (FPR) or fuel injector. If the fuel lines are hot, under hot weather conditions and a hot engine, the fuel will have room to evaporate inside the line, creating a hard-to-start condition.
