Jeep Grand Cherokee won't start despite no check engine light on Jeep Grand Cherokee

Some Jeep Grand Cherokee owners report experiencing starting issues despite the absence of a check engine light, which may indicate underlying electrical system problems. A common cause for this no-start condition is a weak or dead 12v battery, leading to slow or no engine cranking. Additionally, issues such as corrosion or poor connections in the battery cables can prevent the vehicle from starting altogether. Furthermore, a lack of supply to the ignition fuse can result in no cranking, no ignition, and no check engine light activation. To troubleshoot these issues, owners are advised to check the battery for weakness, inspect the battery cables for corrosion or loose connections, and verify the ignition fuse supply to ensure proper electrical flow. Addressing these potential problems may help resolve the starting difficulties with the Jeep Grand Cherokee.
