Diagnosing and Solving Starting Issues in a 2007 Jeep Grand Cherokee Laredo
Have you been experiencing intermittent starting issues with your 2007 Jeep Grand Cherokee Laredo? Don't worry; this article will guide you through the process of diagnosing and resolving the issue.
Professional Diagnosis at a Shop
When faced with intermittent starting problems, it's highly recommended to take your vehicle to a reputable repair shop. The crew there can perform a thorough diagnosis, which might take some time due to the nature of the problem. A professional car repair service can help identify the underlying issue, ensuring your vehicle is back to optimal performance.
Basic Troubleshooting
Before heading to the shop, you can start with some basic troubleshooting steps. Begin by cleaning the battery terminals and posts, making sure they are bright and shiny. Apply a small amount of grease or baseline to the terminals to ensure a good connection. If the problem persists, consider the following steps:
Alternator and Charging System
It’s possible that the alternator is loose and shifting, which could be causing the insufficient charging of the battery. Visit any auto parts store, where they will check the charging system for free. This check can reveal if the alternator is at fault or if there's another issue within the system.
Neutral Safety Switch
Another common issue could be a faulty neutral safety switch. Try shifting the gearstick to park or neutral and attempting to start the vehicle. The starter might not engage if the switch or shifter is not making proper contact. Inspect the key switch or solenoid for any loose connections.
Check for Known Issues in Your Vehicle
Given the nature of your vehicle, it’s important to check if it’s part of the “Power Distribution Center” (PDC) recall. Many Jeeps and other Fiat Chrysler vehicles have been affected by faulty parts. Contact a dealer and provide your Vehicle Identification Number (VIN) to see if your vehicle is included in the recall. If it is, take action to get the necessary repairs made.
Starter Circuit and Fuel System
Common issues often revolve around the starter circuit and fuel system. Perform a basic diagnostic by explaining your issue in detail. Ask if the engine is turning over at the normal speed when cranking. If the engine isn’t cranking, it’s straightforward since the basic starter circuit is similar for many vehicles since the 1960s. Another test you can perform is to spray starter fluid into the intake air duct and see if the engine starts. If it does, the problem likely lies with the fuel system, such as a bad fuel pump, ASD relay, or another component.
Common Solutions
From personal experience, I can share that a bad starter relay, which was often exposed to moisture and corroded, could cause similar issues. Replacing the starter relay, which typically costs around $15, solved a 2005 Jeep with a similar problem.
