How to Fix a Car Engine that Shut Off While Driving

If your car engine shuts off while driving, there are a few things you can do to try and fix the problem. First, check the engine’s oil level.

If the engine still won’t start, check for a loose connection between the spark plug and the coil wire. Repair any broken wires as needed. Finally, if all of these solutions fail, you might need to replace the car’s engine.
