Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello. If the vehicle is just turning off then it is usually either a bad crank position sensor or a bad ignition control module. Both of these are common problems on this vehicle. It can also be an ignition switch but that is not as common. The vehicle will need to be tested while the problem is occurring. A scan tool that reads engine data can be used to check the crank signal when the vehicle stalls. If there is no signal then the sensor is bad. If there is then I would remove the ignition module, which is located under the coil pack, and have it tested at most auto parts stores. I hope this helps. If you need anything else please let me know.
