There are many reasons why a car starts but does not stay running, but one of the most common causes of this problem is a bad fuel pump. When a fuel pump is going out, it is common for a car to stop running abruptly when the fuel supply becomes restricted.Know More
It is also possible that a fuel line is blocked, causing the restriction of fuel. To test whether or not fuel delivery is the cause, the car owner should push down on the gas pedal when the car begins to die. If this does not stop the car from dying, this indicates there is a problem with fuel delivery.
It is also possible that there is a problem with power getting to the engine. One reason for this is a bad alternator. The alternator is responsible for keeping the battery of a car charged. When the alternator goes out, the battery dies. If the car requires a jump after it stops running, the alternator is most likely the problem. When the battery is the problem, there is a clicking sound when the car is turned over.
Unfortunately, there are a number of other possible causes of a car starting but not continuing to run. The ignition wires could be frayed, the timing may need to be adjusted, or the fuel filter may also need to be cleaned.Learn more about Car Parts & Maintenance
When a car is in drive and stalls out, it usually means there is an absence of fuel or spark, a faulty fuel pump or alternator, or some other mechanical failure within the engine itself. There are a number of methods available for testing the problem behind the stalling.Full Answer >
There are several reasons a warm car may stall, including vapor lock, an overheating fuel pump and ignition coils that are cutting out. Overheating ignition coils may also cause a car to stall when warm.Full Answer >
An engine requires air, fuel, and spark to function properly, and when one or more of these components fail, the engine will stall. To confirm what is causing the car's engine to stall, the vehicle's computer will need to be plug into a diagnostics machine.Full Answer >
A leak detection pump in an automobile identifies fuel system leaks that may affect vehicle performance and harm the environment. It does so by pumping air into the fuel tank and charcoal canister so that the engine control module (ECM) can measure the system's pressure decay. Leaks are the most common cause of "check engine" light activations.Full Answer >
