Ford Tempo Ignition Switch Guide: Symptoms and Replacement for 1984-1994 Models
If your Tempo starts but dies as soon as you let go of the key, your ignition switch is the likely culprit.
- The classic symptom of a bad ignition switch on a Tempo is the engine dying as soon as you release the key from the 'Start' position.
- This is a DIY-friendly repair that requires basic hand tools and about an hour of your time.
- A quality aftermarket brand like Standard Ignition is a reliable and cost-effective choice for this repair.
- Do not confuse this issue with a bad TFI ignition module, which typically causes stalling when the engine is hot.
Is Your Ignition Switch Failing? Common Symptoms
The ignition switch on the 1984-1994 Ford Tempo is a common failure point due to age. Unlike the separate, heat-sensitive TFI ignition module that can cause stalling when hot, the ignition switch itself has very distinct symptoms when it wears out. Watch for these specific signs:
- Starts, Then Immediately Stalls: This is the most telling sign for a bad ignition switch on a Tempo. The engine will crank and run as long as you hold the key in the 'Start' position, but it dies the instant you release the key to the 'Run' position. This happens because the switch is failing to send power to the ignition and fuel systems in the 'Run' position.
- No Crank, No Start: You turn the key and nothing happens at all. The internal contacts in the switch that send the signal to the starter solenoid have worn out.
- Intermittent Electrical Problems: Your radio, blower fan, or dashboard lights may flicker or not work at all. Wiggling the key in the ignition might make them work temporarily, pointing to a worn switch.
- Key is Hard to Turn: While this can also be the lock cylinder, binding in the ignition switch can make the key difficult to turn through its positions.
Don't Confuse the Ignition Switch with the Ignition Module
Many Ford Tempo owners experience stalling when the engine gets hot. This is a classic symptom of a failed Thick Film Ignition (TFI) module, a completely different part located on the distributor. The ignition switch, located on the steering column, typically fails in the ways described above, most notably the 'start-and-die' issue.
Choosing the Right Aftermarket Ignition Switch
For a vehicle like the 1984-1994 Ford Tempo, finding original dealership parts is difficult. The good news is that reputable aftermarket brands offer quality replacements that meet or exceed original specifications.
Brand Tiers for Your Ford Tempo:
- OEM-Grade (Motorcraft): Motorcraft is Ford's own parts brand. For electrical components, it's generally considered the highest quality option, ensuring perfect fit and function. If you can find a Motorcraft switch, it's an excellent choice, though it may cost slightly more.
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a well-respected aftermarket manufacturer that produces reliable parts. For this specific repair on a Tempo, a Standard Ignition switch offers a great balance of quality, availability, and value, making it a practical and trustworthy choice.
Pro Tip: The ignition switch is the electrical component located on the steering column, separate from the lock cylinder where you insert your key. In many cases, you only need to replace the switch, not the lock cylinder, which means you can keep your original keys.

Frequently Asked Questions (FAQ)
Do I need special tools to replace the ignition switch?
No, for most 1984-1994 Ford Tempos, you do not need special tools. Basic hand tools like a screwdriver and a socket set are usually sufficient to remove the plastic steering column covers and unbolt the switch. A steering wheel puller is not required for this job.
Was there a recall on the Ford Tempo ignition switch?
No, there were no specific recalls from Ford or the NHTSA for the ignition switch on the 1984-1994 Ford Tempo. There was a major class-action lawsuit and recall related to the TFI ignition module on these cars, which caused stalling, but that is a different part.
Can I still drive with a bad ignition switch?
It is not recommended. If the switch is failing, it can cause the engine to stall unexpectedly while driving, which is a serious safety hazard. If the car won't start or dies immediately, you will be stranded.
Will replacing the ignition switch mean I need a new key?
No. The ignition switch is the electrical part that is separate from the mechanical lock cylinder that your key fits into. You can replace the switch while keeping your original lock cylinder and keys.
