What causes a car to start but not keep running?

The engine requires the right amount of air and fuel to mix together for ignition. If there is a fuel leak somewhere, then the correct amount of fuel may not make it to the combustion chamber. This might be enough to allow the engine to start, but not keep running.

Can a computer malfunction and cause a stall?

An engine control unit, engine control module, or powertrain control module (ECU, ECM, or PCM respectively) is the computer that manages the main engine parameters and programming for the vehicle. Although rare, it is possible for the ECU to malfunction and cause a stall.

Why does my diesel truck not start up?

What causes a car to run lean at idle?

If the root cause is an electrical problem within the idle air control valve itself, you will likely have to replace the IAC. A vacuum leak is a hole in a vehicle’s air intake system behind the mass air flow (MAF) sensor that allows unmetered air into the engine. This throws off the expected air fuel ratio and causes the vehicle to run lean.
