Mitsubishi Eclipse crank no start issue after replacing fuses and O2 sensor on Mitsubishi Eclipse

Some Mitsubishi Eclipse owners report experiencing crank no start issues even after replacing fuses and the O2 sensor. These problems can stem from ignition issues that prevent the engine from starting due to a lack of spark. Additionally, a faulty ECU coolant temp sensor may cause intermittent starting problems or complete failure to start. Owners have also noted that a malfunctioning crankshaft position sensor can lead to a no start condition, similar to issues with the camshaft position sensor, which disrupts the ignition system. Furthermore, problems with the Powertrain Control Module (PCM) may affect various engine functions, including starting the vehicle. Insufficient fuel delivery, potentially caused by issues with the fuel pump, fuel injectors, or fuel pressure regulator, can also result in a crank no start scenario. Lastly, some owners have found that ensuring the starter relay clip is secure and that the starter power and ground cables are properly connected can help resolve starter-related issues. Conducting a thorough diagnostic check is advisable to identify and address the exact cause of the no start issue effectively.
