Will a bad EED relay prevent your car from starting?

Yes, a bad Engine Electronic Distribution (EED) relay can prevent your car from starting. The EED relay is responsible for controlling the power supply to various engine components, and if it malfunctions, it may not provide the necessary power for the ignition system or fuel pump. As a result, the engine may fail to start or could experience intermittent starting issues. It's important to diagnose and replace a faulty relay to ensure proper engine operation.
