I would take a close look at the battery cable connections. Those connections need to be absolutely clean, free from corrosion and tight. ECM/ECU/PCM just acronyms for engine control module, electronic control unit, powertrain control module. It is the computer that controls the engine and a few other functions. Yes, your vehicle has one of those.
