Parts for your 2013 Ford Ranger-Ignition coils

2013 Ford Ranger ignition coils — not used on AU/NZ models

Drawing on technical references including the Ford Australia PX Ranger Owner’s Manual (2013), the Ford T6/PX Ranger Workshop Manual (Section 303 – Diesel Engine and Glow Plug System), Ford Australia/NZ 2013 Ranger specification sheets, and standard diesel ignition principles outlined by Bosch Diesel Engine Management, it’s clear the 2013 Ford Ranger sold in Australia and New Zealand is diesel-only (2.2L and 3.2L Duratorq TDCi). Diesel engines use compression ignition rather than spark ignition, so there are no spark plugs and no ignition coils fitted to these vehicles.

Why aren’t ignition coils used? Diesel combustion is initiated by heat generated from high compression, not by an electrical spark. Instead of coils and spark plugs, the Ranger’s diesel setup uses:

• Glow plugs and a glow plug control module for cold starts
• High‑pressure common‑rail injectors and pump to deliver and atomise fuel
• Engine control module (PCM) to manage timing, fuelling and emissions systems

If an online catalogue shows “ignition coils” for a 2013 Ranger, that listing usually refers to petrol variants sold in other markets (e.g., a 2.5L Duratec). Those petrol models are uncommon in AU/NZ. For local VINs, coils are not applicable.

What should owners service instead of coils? For reliable starting and smooth running, attention should go to:

• Glow plugs: test resistance and current draw if cold starts are slow or smoky, replace as sets when worn
• Battery and cranking voltage: weak batteries cause hard starts and “misfire‑like” shudder on cold mornings
• Fuel system: replace fuel filters on schedule, drain water separators, ensure clean, quality diesel
• Injectors: check balance/leak‑back if there’s rough idle, rattle, or excessive smoke
• Air system: inspect intercooler hoses for splits, keep EGR and intake pathways clean

Owners chasing a “misfire” often assume bad coils. On the 2013 diesel Ranger, coil faults aren’t possible, similar symptoms usually trace to fuelling, air leaks, EGR issues, or battery/charging problems. If in doubt, confirm the engine type via the build plate or VIN, and follow diesel‑specific diagnostic procedures.

Popular questions

Does a 2013 Ford Ranger in Australia or New Zealand have ignition coils?
No. AU/NZ 2013 Rangers are Duratorq TDCi diesels, which don’t use spark plugs or ignition coils. If a parts site asks for coils on this model locally, it’s likely referencing overseas petrol variants.

What replaces the role of ignition coils on the diesel Ranger?
Cold starts are assisted by glow plugs and a glow plug control module, while combustion is driven by compression and precisely metered fuel from the common‑rail injectors. That combination eliminates the need for spark and coils.

I’m getting rough running that feels like a misfire — could it be coils?
Not on the diesel. Check battery health and cranking voltage first, then fuel filter condition, boost hoses for leaks, and injector performance. Diesel “misfire‑like” symptoms are usually air/fuel related rather than an ignition issue.
