A Guide to the 1991-1995 Ford Explorer Starter Solenoid
If you hear a 'click' but your Explorer won't start, the fender-mounted starter solenoid is a likely and easy-to-fix culprit.
- A single click with no crank is the most common symptom of a bad solenoid on this Explorer.
- This part is also called a starter relay and is located on the passenger-side fender wall.
- Replacement is very easy for a DIYer and can be done in under 30 minutes with basic tools.
- Always check that your battery is charged and the terminals are clean before replacing parts.
Is Your Starter Solenoid Failing?
A bad starter solenoid on a 1991-1995 Explorer has classic symptoms that are often confused with a dead battery or a bad starter motor. The most common sign is a single, audible 'click' from the engine bay when you turn the key, but the engine doesn't crank. This usually means the solenoid is receiving the signal from the ignition switch but is failing to send the high-amperage current to the starter. Other symptoms include no sound at all when turning the key, or intermittent starting where the truck starts fine one day but not the next.
Don't Mistake It for a Bad Battery
Before replacing parts, check your battery. If the dashboard lights are dim or don't come on at all, the battery is the likely problem. If the lights are bright and you hear that distinct click from the fender area, the starter solenoid is the prime suspect. Also, ensure your battery terminals are clean and tight, as corrosion can prevent a good connection.

Is this part also called a starter relay?
Yes. For this generation of Ford Explorer, the terms starter solenoid and starter relay are used interchangeably for the same fender-mounted part.
My starter keeps running after the engine starts. Is that the solenoid?
Yes, a starter that stays engaged after the engine is running is a common symptom of a faulty or sticking starter solenoid. The internal contacts can weld themselves together, causing continuous power to be sent to the starter. This should be addressed immediately to prevent damage to the starter motor.
Can I test the solenoid before replacing it?
Yes. A common test is to have someone turn the key to the 'start' position while you listen for a click from the solenoid. A more definitive test involves using a screwdriver with an insulated handle to carefully bridge the two large terminals on the solenoid. If the engine cranks, it confirms the solenoid is bad and the rest of the starting system is likely okay. Use extreme caution when performing this test, as it will create sparks and bypass all safety switches.
