Ignition Coil Guide for the 1975-1981 Nissan 510
Keep your classic 510 running strong with the right ignition coil.
- A failing ignition coil can cause stalling, misfires, or a no-start condition in your 510.
- Aftermarket coils are the only practical option; choose a reputable brand like NGK or Standard Ignition for best results.
- Always inspect the external ballast resistor when replacing the coil, as it can also be a point of failure.
- Replacement is a simple DIY task that can be done in under 30 minutes with basic tools.
Is Your Nissan 510 Ignition Coil Failing?
The ignition coil is a hardworking part that eventually wears out. When it starts to fail, it can leave you stranded. A bad coil might work fine when cold but fail once the engine warms up, causing the car to suddenly stall. Other times, it might prevent the car from starting at all. Watch for these common symptoms.
Common Symptoms of a Bad Ignition Coil
- No-Start Condition: The engine cranks but won't fire up.
- Sudden Stalling: The engine cuts out while driving, sometimes without warning.
- Engine Misfires: The engine sputters, shakes, or runs roughly, especially when you try to accelerate.
- Loss of Power: The car feels sluggish and weak.
- Poor Fuel Economy: You notice you're filling up the gas tank more often.
- Backfiring: You hear loud pops from the exhaust, which can happen when unburned fuel ignites in the exhaust system.
Choosing an Aftermarket Ignition Coil for Your 510
For a vehicle from this era, finding a new original equipment (OEM) ignition coil from Nissan is nearly impossible. The market for the 1975-1981 510 consists almost entirely of aftermarket parts. This is not a bad thing, as many aftermarket brands produce high-quality components that meet or exceed original specifications. The key is to choose a reputable brand.
Aftermarket Brand Tiers
Not all aftermarket parts are created equal. For a critical component like the ignition coil, it's best to avoid the cheapest, no-name options. Based on general reputation and owner feedback in Datsun communities, here is a breakdown of available brands:
- Top Tier (High-Quality Replacement): Brands like NGK and Standard Ignition (SMP) have a long-standing reputation for producing reliable ignition components that are often trusted as OEM suppliers for many carmakers. Choosing a coil from one of these brands is a solid investment for reliability.
- Standard Tier (OEM-Equivalent): Brands such as Spectra and Walker Products aim to provide direct-fit replacements that perform like the original part. They are generally considered a good balance of price and quality for a daily driver or restoration project.
- Economy Tier (Value-Oriented): Brands like DriveWire and Global Parts focus on providing the most affordable options. While functional, their long-term durability may not match that of the higher-tier brands. These are best for budget-conscious repairs where getting the car running is the top priority.

Frequently Asked Questions
Is it hard to replace the ignition coil on a 1975-1981 510?
No, it is a very easy job for a DIYer. The coil is typically mounted to the fender or firewall with one or two bolts. The process involves disconnecting the battery, unplugging the two small wires, removing the main high-tension lead that goes to the distributor, unbolting the old coil, and installing the new one.
My car has no spark. Is it definitely the ignition coil?
Not necessarily. While the coil is a common suspect, Datsun enthusiasts often point to other potential issues first. Check for loose or broken wires, a faulty ballast resistor, or problems inside the distributor (like the points, condenser, or electronic module if equipped) before replacing the coil.
Are there any recalls for the ignition coil on my Nissan 510?
No, there are no known recalls or technical service bulletins (TSBs) from Nissan or the NHTSA for ignition coil issues on the 1975-1981 Nissan 510. Any failures are due to the age and normal wear of the component.
Do I need a special type of coil?
Yes, you need to match the coil to your ignition system. Most of these cars use an external ballast resistor, which requires a specific type of coil. Using a coil designed for a system without a resistor can lead to poor performance or premature failure. Always verify the part is correct for your specific year and model.
