What are the reasons for the ignition coil not firing in Mitsubishi Pajero?

The reasons for the ignition coil not firing in Mitsubishi Pajero are: 1. Damaged ignition coil; 2. Open circuit in the wiring between the main relay, speed sensor, computer, and ignition coil. Taking the 2020 Mitsubishi Pajero as an example, it belongs to the mid-to-large SUV category, with body dimensions of: length 4900mm, width 1875mm, height 1900mm, wheelbase 2780mm, fuel tank capacity 88l, and curb weight 2155kg. The 2020 Mitsubishi Pajero features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a 3.0l naturally aspirated engine, delivering a maximum horsepower of 174ps, maximum power of 128kw, and maximum torque of 255nm, paired with a 5-speed automatic transmission.
Recently, my Mitsubishi Pajero's ignition coil failed, and I've summarized a few key lessons. The coil itself might have burned out—over time and under high temperatures, it's prone to aging or internal short circuits, preventing it from generating the high voltage needed for the spark plugs. Next, check the fuse; the central control box has a dedicated ignition circuit fuse—if it's blown, no power reaches the coil. Also, inspect for loose or corroded wiring connections—Pajero's connectors can loosen from vibration, so use a multimeter to test for abnormal resistance. Sensors play a big role too; for example, a faulty crankshaft position sensor can send incorrect signals to the ECU, causing the coil to stop responding. Additionally, unstable battery voltage (below 12V) triggers system protection, shutting off ignition. Troubleshoot from simple to complex: replace the fuse, clean connectors, test coil resistance (normal range: 1-2 ohms), and seek professional help if needed. Don’t delay fixing this—hard starts and engine damage can follow. After replacing the coil myself, the car runs much smoother.
