To check the resistance on a coil pack for a 2003 Trailblazer, first, disconnect the electrical connector from the coil pack and remove it from the engine. Use a digital multimeter set to the ohms (Ω) setting, and measure the resistance across the primary terminals (usually the two larger pins). The typical resistance should be between 0.5 to 2.0 ohms. If the reading is outside this range, the coil pack may be faulty and should be replaced.

How do you check coil on 2003 Nissan?
To check the ignition coil on a 2003 Nissan, start by visually inspecting the coil for any signs of damage or corrosion. Use a multimeter to measure the primary and secondary resistance of the coil; the primary resistance should typically be between 0.5 to 2.0 ohms, while the secondary resistance should be around 6,000 to 15,000 ohms. Additionally, you can perform a spark test by removing the coil and connecting it to the spark plug, then cranking the engine to see if a spark is generated. If the coil fails any of these tests, it may need to be replaced.
