Autozen, the pumps were old probably original. Around early March of this year they started to make a buzzing sound which is indicative of pumps going bad so I had the pumps and filter replaced. Everything was fine until last week when the car shut down on a hot day after about 15-20 minutes of driving and it would not start until it cooled down. After restarting it shut down again after about 5 minutes or so until it cooled down. After reading the archives I decided to also replace the crank sensor.

Since the MAS and the crank shaft sensor were original I just did not want to take a chance of the car shutting down so I decided to replace both.
