Problem overview

Some Mazda B3000 owners report experiencing engine shutdowns while driving, which may restart after a few minutes. This issue can occur even after replacing the fuel pump and sensor, potentially due to a faulty crankshaft position sensor, MAF sensor, MAP sensor, or engine control unit. Malfunctioning components can disrupt the engine's proper functioning and fuel system, leading to stalling. It is crucial for owners to have these components accurately diagnosed and repaired to prevent future engine shutdowns while driving.
