Why would a car start and then die?
An engine may start successfully but stall shortly afterward when one of the systems required to keep it running is missing or operating incorrectly.
The fault can be electrical, mechanical, fuel-related, or security-related.
Possible causes
- Fuel pressure problems
- Injector problems
- Crankshaft or camshaft sensor faults
- Air or vacuum leaks
- Throttle-body problems
- Immobilizer authorization issues
- Power supply or ground problems
- Engine-control module faults
What should be checked?
A technician should compare the vehicle's symptoms with scan data and test the systems involved rather than assuming the first suspected component is defective.
