Parts for your 2000 Nissan Navara-Ignition coils

2000 Nissan Navara ignition coils: petrol models use them, diesels don’t

On the 2000 Nissan Navara (D22), ignition coils are fitted to the petrol KA24DE models and not used on the diesel variants (TD27, QD32, YD25). This is confirmed by Nissan’s D22 Factory Service Manual for KA24DE (EC/IG sections list the ignition coil and high-tension leads), while the diesel engine manuals detail glow plugs and fuel injection with no spark ignition hardware. The Nissan parts catalogue for D22 likewise lists an ignition coil for KA24DE only. Sources: Nissan D22 FSM – Engine Control (KA24DE), Ignition, Nissan D22 Diesel Engine manuals (TD27/QD32/YD25), Nissan FAST/parts catalogue for D22.

For owners of 2000 Navara petrol utes, the ignition coil’s job is to step up battery voltage to the high energy needed to fire the spark plugs. On KA24DE models, a single coil feeds the distributor and leads, delivering spark to each cylinder right when the ECU calls the shots. Healthy coils keep starts crisp, idle smooth, fuel economy tidy, and towing torque on song.

There’s no fixed service interval for the coil itself, but it should be checked whenever the bonnet’s up for plugs, leads or a tune. Typical signs a coil’s on the way out include:

• Misfire under load or at idle, sluggish take-off, rough cold starts
• Poor fuel economy, raw fuel smell, or a check engine light (codes like P0300–P0304)
• Cracked housing, carbon tracking, or burnt connectors on inspection

Good practice during servicing:

1. Test the coil against the factory resistance/spec values in the D22 FSM and verify spark output.
2. Replace spark plugs and high-tension leads on schedule, tired leads can cook an otherwise good coil.
3. If swapping the coil, disconnect the battery, label the leads, and mount the new unit securely. Use dielectric grease on boots and keep routing tidy to avoid arcing.
4. Clear fault codes and road test under load to confirm the fix.

Quality matters. An OE-spec coil typically outlasts cheapies, especially with the heat and corrugations common across Aus and NZ. If the ute’s a diesel, there’s no ignition coil at all—diesels rely on compression ignition and, when fitted, glow plugs for cold starts—so any hard-start or miss issues are on the glow, fuel, or air side, not ignition.

Popular questions about 2000 Nissan Navara ignition coils

Does a 2000 Navara have ignition coils?
Petrol KA24DE models do. Diesel variants (TD27, QD32, YD25) don’t use ignition coils because they ignite fuel by compression and may use glow plugs for cold starts. This layout aligns with the D22 Factory Service Manual and Nissan parts listings for the era.

How often should ignition coils be replaced?
There’s no set interval. Replace only when testing or symptoms point to a fault. Inspect the coil, plugs and leads during regular services, many coil “failures” trace back to worn leads or incorrect plug gaps stressing the coil.

What are the common symptoms of a failing coil on a KA24DE?
A rough idle, misfire under load, hard starting, higher fuel use, and stored misfire fault codes (P0300–P0304). Physical signs include cracks in the coil body or burnt connectors.
