Twice in the last week, I have had to have my 92 Acura Integra jump started. My battery is less than two months old. This seems to occur when I've been out and made several stops. Once I get home and park the car, a fan runs under the hood for a prolonged time, usually about an hour. The next morning, the car won't start.

Hello,

It sounds like a faulty coolant temperature sensor. As the sensor is likely sending signal tot eh ECM that the engine is 'too hot' and the fan runs to cool it down.

The coolant temperature sensor works by increasing / decreasing resistance with the engine temperature. It can fault and have excess resistance, which will signal that the engine is too hot.

Here are some helpful articles:
