Ford Ghia Ignition Control Module: A Guide for 1991-1994 Models
If your Ford Ghia stalls when it's hot and restarts after cooling down, the ignition control module is the most likely cause.
- The primary symptom of failure is the engine stalling when hot and restarting only after it cools down.
- This part is known as a TFI (Thick Film Ignition) module, and heat is its main cause of failure.
- When replacing the module, you must apply the new thermal paste to the metal backing to prevent the new part from failing.
- While OEM Motorcraft is preferred by some, a quality aftermarket brand like Standard Ignition is a practical and available solution.
Is Your Ghia Stalling When Hot? It Could Be the Ignition Module.
The single most common problem pointing to a bad ignition control module in a 1991-1994 Ford is an engine that runs fine when cold, but suddenly stalls after it has warmed up. The car may then refuse to start until the engine has cooled down for 20-30 minutes. This is a classic sign of heat-related failure inside the module. Because this part is so sensitive to heat, its original placement on the hot engine distributor on many Fords made failure a common issue.
Symptoms of a Failing Ignition Control Module
A bad module can cause problems that come and go at first, but they will get worse over time. Watch for these signs:
- Engine Stalls When Hot: The engine cuts out in traffic after warming up, but may restart after it cools.
- No-Start Condition: The engine cranks over but will not fire up because there is no spark. This can be intermittent before the module fails completely.
- Rough Running and Misfiring: The engine may hesitate, run rough, or feel like it's down on power.
- High RPM Break-Up: In some cases, the engine may start to sputter or cut out at higher RPMs, feeling like it's hitting a rev limiter.
Heat is the Enemy
The ignition modules on these Fords are known for failing due to high engine temperatures. The electronic components inside the module are sensitive and can break down when they get too hot, causing intermittent stalling or a complete no-spark condition.
Choosing the Right Aftermarket Part: Standard Ignition
Finding a brand-new OEM Motorcraft ignition module for a vehicle of this age is difficult. The aftermarket is the primary source for this part. Standard Motor Products (brand name: Standard Ignition) is a well-known manufacturer of replacement ignition components. Forum discussions among Ford owners show mixed experiences with aftermarket modules in general; some have no issues, while others find they don't last as long as the original Motorcraft part. However, for a 1991-1994 vehicle, a quality aftermarket part from a reputable brand like Standard is a reliable and practical choice. When two options are available from the same brand, it often represents a standard and a premium tier, with the latter potentially offering more robust components.
Apply Thermal Paste!
Your new ignition module will come with a small packet of white or gray thermal paste. You MUST apply a thin layer of this paste to the metal back of the new module before installing it. This paste helps transfer heat away from the module to the distributor or heatsink, preventing the new part from quickly overheating and failing. Do not use dielectric grease; it is an insulator and will cause the module to burn out.

Frequently Asked Questions (FAQ)
Can I replace the ignition module myself?
Yes, this is a DIY-friendly job for most home mechanics. The module is usually located on the side of the distributor. You may need a special thin-walled 5.5mm (or 7/32") socket to remove the small bolts holding it in place. The most important step is applying the included thermal paste to the new part.
Were there any recalls for this part?
No, there were no specific safety recalls issued by the NHTSA for the ignition control module on 1991-1994 Ford models like the Escort. However, the tendency for these modules to fail from heat is a widely known issue among mechanics and owners.
What happens if I don't replace it?
A failing ignition module will not fix itself. The stalling and no-start problems will become more frequent until the module fails completely, leaving you stranded. It is a safety risk if the engine stalls while driving in traffic.
Could the problem be something else?
Yes, although the module is the most common cause for these symptoms, a similar issue can be caused by a failing Profile Ignition Pickup (PIP) sensor located inside the distributor. However, replacing the ignition module is often the first and most direct solution to try, as it is easier to access.
