Ignition Coils For 2003 Nissan Murano

 

The 2003 Murano has a 3.5L V6 (VQ35) engine. This engine has 6 independent ignition coils that sit right above each spark plug. When these coils go bad, the engine will run rough, or feel like it's "chugging" along as you drive the vehicle.  This can be accompanied by a check engine light, and error codes such as P0301 (cylinder #1) through P0306 (cylinder number 6). We have these ignition coils are much less than the local auto parts store does. If the ignition coils in your 2003 Murano appear scorched or burnt, it's best to check the main ground cable before proceeding to replace the ignition coils. The main ground cable connects from the negative terminal on the battery to the transmission. Many owners have reported this ground cable breaking off, which causes the ignition coils to literally burn/fry up. This can also cause damage to the ECU in your Nissan Murano. If it appears corroded, replace it before you change your ignition coils or you will find the brand new ignition coils burnt up very rapidly. In some cases as soon as you start your Murano. This was a common problem that many Murano owners had, and out goal is to inform you of this issue so you can save money, and avoid purchasing ignition coils twice.

 

Common Reasons For Ignition Coil Pack Failure in 2003 Nissan Murano

 

We already covered the main ground cable issue. A rusted or broken ground cable will certainly cause the ignition coils to fail. bad engine mounts may accelerate this issue as well, so if you feel a noticeable "thud" while accelerating from a stop, that means you may possibly have a broken engine mount which is allowing the engine to move around more than it's supposed to, and the ground cable can break off in this type of incident. If the ground cable checks out, then the ECU is the next thing to look at. This is only a concern in the Murano if the ground cable has broken at any point in time. The ECU and ignition coils are the main items that sustain damage. If the ECU checks out too, then other reasons for ignition coil failure are leaking coolant, improper engine bay washing, or simply just old ignition coils. As these age together in the same exact environment, they will fail within a short period of time from each other. it's never instant, but it can be a few days apart. It's similar to headlight bulbs. When one fails, the other isn't too far away from failure as well, so don't give up on your Murano if you get more than one failure within a short period of time. This can happen to any vehicle, old and even newer vehicles.
