How can you tell if a starter relay is bad?
Set your multimeter to be on the Ohms scale. Place one probe on the lead on the ignition circuit terminal and the other on the ground lead. The reading should be less than 5 Ohms. If it’s more than that, the starter relay is faulty and needs to be replaced.
How do you change a starter relay?
How to Install a Starter Relay

Will a car start without a starter relay?
The starter relay not only completes the electrical circuit but also increases the current from the battery. If your starter relay fails, the electrical signal from the battery to the starter motor will never reach it. As a result, no matter how many times you turn the key, your engine will not start.
