Dodge B350 Ignition Coil Guide for 1981-1994 Models
Everything you need to know about choosing the right ignition coil for your 1981-1994 Dodge B350 van.
- A failing ignition coil is a very common cause of no-start or stalling issues on these vans.
- The replacement is a simple, beginner-friendly DIY job that takes less than 30 minutes.
- Other common failures like the ASD relay or crank sensor can show similar symptoms, so diagnosis is key.
- Investing in a quality aftermarket brand like Bosch, Delphi, or Standard Ignition is recommended for reliability.
Symptoms of a Failing Ignition Coil
Ignition coils on these older Dodge Vans can fail from age, heat, and vibration. When a coil starts to go bad, it usually gives you some warning signs. A completely failed coil will prevent the van from starting at all. Here’s what to look for:
- No Start or Hard Starting: The most common symptom is the engine cranks but won't fire up. 🎬 Watch this guide if your van cranks but won't start. You may also find it takes longer than usual to start.
- Stalling: The engine may start and run for a few minutes, then suddenly die, especially as it warms up. This can be intermittent, making it tricky to diagnose.
- Rough Idle and Misfires: A weak coil produces a weak spark, which can cause the engine to run rough, shake, or misfire.
- Poor Performance: You might notice the van feels sluggish, hesitates during acceleration, or gets worse gas mileage than usual.
- Visible Damage: Sometimes you can see cracks in the coil housing or signs of melting or burning.
Choosing the Right Aftermarket Ignition Coil
For a vehicle from this era, original Mopar parts are often discontinued or hard to find. Thankfully, modern aftermarket coils are high quality and often exceed the original specifications. Here’s a breakdown of available brands:
Brand Quality Tiers
Premium Brands (OEM Quality or Better):
- Bosch, Delphi, NGK, Standard Ignition (SMP): These are top-tier manufacturers known for reliability and performance that meets or exceeds original factory standards. They use high-quality materials and windings for consistent, strong spark. Choosing one of these brands is a safe bet for longevity and trouble-free operation.
- MSD: This is a performance-focused brand. An MSD coil is a great upgrade if you want a hotter, more powerful spark, which can improve throttle response, especially on modified engines.
Mid-Grade & Value Brands:
- Spectra, WAI Global, Walker Products: These brands offer a good balance of quality and price. They are reliable choices for a daily driver and a significant step up from no-name online parts.
Economy Brands:
- DriveWire, Global Parts: These are budget-friendly options that will get your van back on the road. While they meet basic requirements, their long-term durability may not match that of premium brands.
Typical Repair Costs
Replacing the ignition coil on a 1981-1994 B350 is an inexpensive repair, whether you do it yourself or have a shop handle it.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Ignition Coil | $20 - $106 |
| Shop Labor | $50 - $120 |
| Total Professional Repair | $70 - $226 |
Frequently Asked Questions
Is this a difficult repair to do myself?
No, this is a very easy DIY job. The ignition coil is usually mounted to the engine or firewall with a simple bracket held by one or two bolts. You just need to disconnect the battery, unplug the electrical connector, unscrew the high-tension wire from the distributor, and unbolt the coil. The whole process typically takes less than 30 minutes with basic hand tools.
🎬 Watch a step-by-step walkthrough of a coil replacement and upgrade.Are there any recalls or TSBs for the ignition coil?
There are no active recalls or technical service bulletins (TSBs) from the NHTSA specifically for ignition coil failure on the 1981-1994 Dodge B350. Most issues are related to the part's age and normal wear.
Do I need a special type of coil?
Most 1981-1994 Dodge B350s use a traditional, canister-style ignition coil. Some earlier models may have used an external ballast resistor, but later electronic ignition systems do not require one. It is crucial to buy a coil specified for your exact year and engine (e.g., 5.2L/318 or 5.9L/360) to ensure it has the correct internal resistance and voltage output. Using the wrong coil can lead to it burning out quickly or damaging other ignition components.
My van has no spark. Is it definitely the coil?
Not necessarily. While the coil is a common culprit, a no-spark condition on these vans can also be caused by a failed Auto Shutdown (ASD) relay, a bad Hall Effect pickup sensor in the distributor (also called a cam sensor), or a faulty crankshaft position sensor. It's important to test for power at the coil before replacing it. 🎬 See how to test your ignition coil with a multimeter. If you have 12 volts going into the coil but no spark coming out, the coil is likely bad.
