Parts for your 2014 Ford Ranger-Ignition coils

2014 Ford Ranger ignition coils — what’s fitted and what’s not

For Australia and New Zealand–market 2014 Ford Ranger (PX series), ignition coils aren’t a thing on the common engines. Those utes were sold almost exclusively with Duratorq TDCi diesels: the 2.2‑litre inline‑four and 3.2‑litre inline‑five. Diesel engines use compression ignition, so there are no spark plugs and no ignition coils to service. A petrol 2.5‑litre Duratec existed in some overseas markets, and that variant does run coil‑on‑plug ignition — but it’s rare locally.

Technical sources that outline this: Ford Workshop Manual (Ranger PX 2011–2014, Sections 303‑00 and 303‑04C) describes the Duratorq TDCi as compression‑ignition with glow plugs, not spark ignition, Ford global parts catalogues (Microcat/ECAT) list no ignition coil for the 2.2/3.2 TDCi VIN codes, and the Haynes Ford Ranger & Mazda BT‑50 Diesel (2011–2016) manual confirms coil‑less diesel ignition architecture.

Why no coils on these Rangers? Diesel combustion relies on very high compression and hot air in the cylinder to ignite the fuel. An ECU‑controlled common‑rail system meters fuel via high‑pressure injectors, and glow plugs assist cold starts. Because there’s no spark, there’s no coil pack or coil‑on‑plug hardware to fail or maintain.

If a 2014 Ranger diesel is misfiring, down on power, or hard to start, think fuel and air, not ignition. Typical checks under the bonnet include:

• Fuel system: clogged fuel filter, contaminated diesel, injector balance, or high‑pressure pump performance
• Air and boost: split intercooler hoses, boost leaks, dirty air filter, MAF/MAP sensor faults
• EGR and DPF: sticking EGR valve or high soot load affecting drivability
• Glow plugs and relay: for rough cold starts or excessive cranking

If you do have an import or fleet 2.5‑litre petrol Ranger, it uses coil‑on‑plug modules. In that case, treat coils as wear items: watch for misfire under load, rough idle, or a flashing MIL, and replace coils and spark plugs in matched sets when needed. Use quality parts, keep plug gaps to spec, and avoid washing coils with solvents.

FAQs

Does my 2014 Ford Ranger have ignition coils?
If it’s the common 2.2 or 3.2 TDCi diesel sold in Australia or New Zealand, no — there are no ignition coils or spark plugs. A small number of overseas‑market petrol 2.5 models use coil‑on‑plug ignition.

What should I service instead of ignition coils on a diesel 2014 Ranger?
Focus on fuel and air: replace the fuel filter on schedule, use quality diesel, keep the air filter clean, and check for boost hose leaks. Glow plugs and their relay are also worth testing if cold starts are rough.

I’ve got a misfire — could coils be the cause on my 2014 Ranger?
On diesel models, a misfire won’t be from coils because there aren’t any. Look at injector performance, fuel pressure, air‑metering sensors, EGR operation, and compression. On rare petrol variants, failing coil‑on‑plug units can cause misfires, especially under load.
