QUESTION: Here is a problem that I have fought for almost two years. My 2001 Buick Regal will not start after a shutdown and heat soak. The car has 128,000 miles, never shuts down while driving, and starts and runs perfectly in the morning. When it won't restart, you can crank it until the battery runs down but the car won't start. After shutting the engine off, it will start immediately – if you don't wait too long!
