Hi my name is***** will be glad to help. Check for power to the ECM. Is the check engine light coming on and cycling with the key?

Customer: replied 1 year ago.
No. The light is not turning on like usual

That means the ECM is not communicating from either a loss of power or ground or a faulty ECM. Check for inline fuses between the battery box and ECM and for wiring from the POS terminals of the battery for corrosion and damage as well. Check your fuses and relays as well as power in and out of your IGN switch. Let me know
