if your ecm is bad, first off the car won't start, your fuel pump won't work, no spark, basically everything shuts down Ok the above can be symptoms of a bad ECM, But that's not the only answer. Your car's Check Engine light will definitely be on. Your car may run like the timing is off, and not get up to speed. Get someone (a mechanic or Auto Zone) to run their code scanner on your car. If it throws out codes that show Ignition Coil A-E failure, CKP and CMP imminent failure, TPS and Pedal Sensor High Circuit, TPS and Pedal Sensor Low Cicuit, MAP and BARO Sensor High and Low. Then you definitely need to get the ECM checked out and replaced. This just happened top a car I worked on and when the ECM was replaced it fixed everything.
