How to Tell If a Starter Relay Is Bad in a Ford

21

A bad starter relay on your Ford vehicle will prevent the necessary electrical power from reaching the starter motor; fail to cut off power; or keep the motor from starting at all. Fortunately, all Ford models have a remote relay near the battery, which makes it easy and convenient for troubleshooting. This guide will help you determine whether the starter relay on your Ford has gone bad, using a jumper wire and a multimeter.

Step 1

Disable the ignition system. If your Ford comes equipped with a distributor, unplug the ignition coil from the distributor, and ground it to the engine with a jumper wire. If your vehicle is not equipped with a distributor, you can remove the fuel pump relay or fuse for these tests.
