Mazda MPV intermittent shutdown and no crank issue possibly related to faulty ECM on Mazda MPV

Some Mazda MPV owners report experiencing intermittent shutdowns and no-crank issues, which may be attributed to a faulty Engine Control Module (ECM). These problems can indicate ECM malfunction, potentially preventing the engine from starting or cranking at all. The ECM is vital for managing engine functions such as fuel injection and ignition timing, and its failure can significantly impact overall vehicle performance and control. Additionally, some owners find that their vehicle may crank without starting or may not crank at all due to ECM issues. It is recommended that these owners seek professional diagnosis to accurately identify the problem and determine the necessary repairs or replacements.
