Is Your Ignition Coil Failing?
A bad ignition coil on this generation of Ford truck often causes problems that appear suddenly. The most common complaint is the engine stalling for no reason, especially after it has warmed up. It may start again after it cools down, only to repeat the problem later.
Key Symptoms of a Bad Coil:
- Engine cranks but won't start: This is a classic sign of a dead coil where there is no spark being created.
- Sudden stalling: The engine cuts out while driving, often when hot.
- Rough running or misfiring: The engine may sputter, shake, or feel like it's losing power.
- Intermittent spark: The coil may work sometimes and fail at other times, making the problem hard to diagnose.
Pro Tip: Finding the Coil
To locate the ignition coil, look on the driver's side of the engine bay. It's a square or canister-shaped part mounted to a metal bracket. The easiest way to find it is to follow the thick wire coming from the very center of the distributor cap directly to it.
Choosing the Right Aftermarket Ignition Coil
For a stock 1993-1997 P-350, you don't need a high-performance racing coil. A quality standard replacement will work just fine and restore original performance. Aftermarket coils are generally a cost-effective option, but quality can vary between brands.
| Tier | Brands | General Assessment |
|---|---|---|
| Good Quality Aftermarket | Standard Ignition (SMP) | Standard Motor Products is a well-known brand that has been around for a long time. It's generally considered a reliable choice for replacement parts. If available, choose their standard line over their budget "T-Series". |
| Standard/Value | Spectra, WAI Global | Spectra is a common aftermarket brand offering standard replacement parts. WAI Global is often positioned as an OE-equivalent, but user reviews can be mixed, with some reporting success and others experiencing early failures on different parts. These brands can offer good value but may have less consistent quality control than premium lines. |
| Economy | Global Parts, Skyward | These brands fall into the economy category. They are the most affordable but may not have the same durability or long-term reliability as higher-priced options. Specific reviews for their ignition coils are not readily available. |
OEM vs. Aftermarket
The original Motorcraft coil in your truck was built to a high standard. While a quality aftermarket part from a brand like Standard Ignition is a perfectly good replacement, be cautious with the cheapest economy options. For a critical part like an ignition coil, spending a few extra dollars for a reputable brand can prevent you from being stranded later.
Replacement Overview
Replacing the ignition coil on this truck is a simple job that most owners can do themselves. It involves unplugging the electrical connector, removing the main spark plug wire, and unbolting the coil and its bracket, which is held on by four small bolts.
Frequently Asked Questions (FAQ)
Can I drive with a failing ignition coil?
It is not recommended. A failing coil is unpredictable. It can cause the engine to stall suddenly in traffic, which is a serious safety risk. If you suspect your coil is bad, it's best to replace it as soon as possible.
How do I test my ignition coil?
The most basic test is to check for spark. You can use an inline spark tester between the coil wire and the distributor. If there's no spark when cranking the engine, and you've confirmed the coil is getting power, the coil itself is likely bad. You can also test the primary and secondary resistance with a multimeter, but you will need the correct specifications for your coil.
Are there any recalls for the ignition coil on my P-350?
No, there are no active recalls or common Technical Service Bulletins (TSBs) from Ford for ignition coil failure on the 1993-1997 Ford P-350.
Should I replace my spark plugs and wires at the same time?
It's a good idea. Old, high-resistance spark plug wires can put extra strain on a new ignition coil, potentially causing it to fail prematurely. If your wires, distributor cap, and rotor are old, replacing them with the coil is good preventative maintenance.
