If your 2001 Nissan Frontier is experiencing a no spark and no crank issue even after changing the distributor cap, there are a few things that could be causing the problem. Here are some possible causes and solutions:
-
Faulty ignition coil: The ignition coil is responsible for generating the high voltage needed for the spark plugs to ignite the fuel mixture in the engine. If the ignition coil is faulty, it can prevent the engine from starting. You may need to replace the ignition coil.
-
Bad crankshaft position sensor: The crankshaft position sensor detects the position of the crankshaft and sends this information to the engine control module (ECM). If the sensor is faulty, it can prevent the engine from starting. You may need to replace the crankshaft position sensor.
-
Failed ECM: The engine control module (ECM) controls many of the engine's functions, including the ignition system. If the ECM is faulty, it can prevent the engine from starting. You may need to replace the ECM.
-
Loose or damaged wiring: Loose or damaged wiring can cause issues with the ignition system and prevent the engine from starting. Check all wiring connections and repair or replace any damaged wiring.
-
Failed starter: If the starter motor has failed, it will prevent the engine from cranking. You may need to replace the starter motor.
I recommend having a professional mechanic diagnose the issue to determine the exact cause of the problem and make the necessary repairs. They can perform tests to pinpoint the issue and ensure that your vehicle is fixed correctly.
