Hello. If the motor will only stay running with starting fluid, you likely have a fuel delivery issue. This can happen for a variety of reasons ranging from low fuel pressure to bad injector pulse to even just a dirty set of injectors. I would recommend having an expert from YourMechanic come to your home to diagnose why your car is dying after starting and make the necessary repairs.
