Depending on whether the engine is hot or cold, there are a couple different reasons why a car might start with no problem but stall shortly afterwards. If the problem only happens when the engine is cold, a bad electric sensor is likely to blame. If the car stalls even when the engine is warm, the cause is likely a faulty electric fuel pump.Know More
A bad electric sensor can only occur on a car with a fuel injection system. Under this scenario, one of the electronic sensors has gone bad and is causing the car's computer to malfunction and improperly calculate the amount of fuel the engine needs. If it's cold outside or the engine is cold, the sensors are not sensing the low temperature, therefore the engine is not maintaining the appropriate air-to-fuel ratio to keep it running.
A faulty electric fuel pump is also a problem limited to cars with a fuel injection system. A whirring sound can be heard coming from the engine when the fuel pump is working correctly. If this pump fails, the engine will not receive enough fuel to keep it running after starting.
A qualified mechanic can troubleshoot, diagnose and confirm the source of the problem. It is a relatively simple job to replace a faulty sensor or electric fuel pump.Learn more about Car Parts & Maintenance
There are several different problems that might cause a car to stop running or stall while it is being driven; however, according to CarsDirect, the three most likely culprits are issues with the electrical system, fuel system or vacuum system. A variety of issues anywhere along the line could cause your car to stall out while idling, or even in the middle of being driven.Full Answer >
A car can stop running while driving if it runs out of fuel or because of malfunctioning components such as alternators, fuel pumps, ignition switches or sensors. Drivers can attempt restarting the engine or gently guiding it to the side of the road if restarting fails.Full Answer >
The Check Engine or Service Engine Soon indicators illuminate when responding to a sensor detecting a problem, and the indicator generally stays on until the problem is repaired. If the indicator light goes off, it can mean the car auto-corrected the problem or the sensor emitting the warning is faulty.Full Answer >
A ticking engine is usually an indication of a problem with the valvetrain. The actual issue isn't always obvious and could be mechanical problems, an incorrect filter or a failing oil pump.Full Answer >
