Why is my Ford Expedition not starting?

Troubleshooting a Ford Expedition That Won’t Start
If your Ford Expedition is not starting, there are several potential causes to consider. Here are some common issues and troubleshooting steps based on the information from the search results:
1. Battery Issues:
– A test can be done to measure the voltage between the battery poles, check the acid level, and assess the condition of the starter battery. If a new car battery has been installed, it may not have yet reached its full capacity. A new battery only develops its full capacity over time.
– If the voltage drops to below 10.5 volts when attempting to start the engine, the battery is likely bad and needs to be replaced.
2. Ignition System and Spark Plugs:
– Without functioning spark plugs, the engine will not start. The spark plugs themselves are often not affected by a defect. Instead, plug connections on the ignition system may come loose. If only one plug is actually loose, it can be fixed on site. If a spark plug has failed, it must be replaced in the workshop.
3. On-Board Diagnostics (OBD):
– Since the Ford Expedition is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located.
4. Mechanical Failure and Starting Circuit:
– A technician will immediately go for the most common problems first, including the electrical system, the ignition system, fuel system, computer or components within its sphere of influence, the security system, and a mechanical failure in the engine. Checking the starting circuit is also important.
5. Other Potential Causes:
– Rodent damage can be another reason why your Ford Expedition won’t start.
It’s important to consider these potential causes and perform the necessary tests or inspections to identify the specific issue preventing your Ford Expedition from starting. If the issue persists, seeking professional assistance may be necessary.
