Gasoline Ram 1500s use one ignition coil per cylinder: 6 coils on the 3.6L V6 and 8 coils on the 5.7L V8. The EcoDiesel 3.0L uses diesel ignition and has no ignition coils. Availability varies by model year and trim.
This article explains how ignition coils are configured across the Ram 1500's current engine lineup, and what that means for maintenance and troubleshooting.
Engine options and ignition configurations
Two gasoline engines and one diesel power the Ram 1500 lineup. The count of ignition coils depends on whether the engine uses spark ignition or compression ignition. The following breakdown applies to typical coil-on-plug setups.
- 3.6L Pentastar V6 (gasoline) — 6 ignition coils (one per cylinder)
- 5.7L Hemi V8 (gasoline) — 8 ignition coils (one per cylinder)
- 3.0L EcoDiesel V6 (diesel) — no ignition coils (diesel uses glow plugs for preheating)
In other words, if your Ram 1500 is equipped with a gasoline engine, you should expect one ignition coil for each cylinder present. The diesel model does not use spark-ignition coils.
Maintenance considerations
Coil-on-plug systems on the gasoline engines are generally reliable but can fail with age and heat, leading to misfires. If you experience rough running or misfires on a Ram 1500 with the 3.6L or 5.7L, coil-pack or spark-plug replacement can be part of the service. The EcoDiesel's glow plugs require a different maintenance approach and are not interchangeable with spark-ignition coils. Always verify the engine type and consult the owner's manual or dealer for the exact coil arrangement by model year.
Summary
The answer to how many ignition coils a Ram 1500 has depends on the engine. Gasoline versions with the 3.6L V6 have six coils, and those with the 5.7L V8 have eight. The EcoDiesel uses glow plugs and has no ignition coils. Always confirm the engine of your specific Ram 1500 to determine the exact ignition-coil count and maintenance needs.
How long do coil packs last on a Ram 1500?
In general, however, ignition coils can last anywhere between 120,000 to 150,000 miles or five to seven years.
Will a car start if all 4 ignition coils are bad?
Since coil packs supply the voltage that powers the spark plugs, a total failure means no spark, and without a spark, the engine won't run. If just one coil pack is failing, your car may still start but could run poorly.
How many ignition coils does a Ram 1500 have?

How much does it cost to replace ignition coils on a Dodge Ram 1500?
The average cost for a Dodge Ram 1500 Ignition Coil Replacement is between $153 and $227. Labor costs are estimated between $46 and $67 while parts are priced between $107 and $160. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
