Troubleshooting a Ford Expedition that does not start requires a systematic approach that rules out problems with the electrical system, spark and fuel before moving to issues that are more complex. The time to troubleshoot the issue depends on the cause of the failure to start.Know More
Start by cleaning the battery connections. Once they are clean, if the Explorer does not start, use a battery tester to check the condition of the battery. If you do not have a battery tester, attempt to jump-start the vehicle. If it starts, take it to a parts store for battery testing, and replace the battery if it is bad.
If there is no spark, the engine does not ignite the fuel to start. Check the coil, using a multi-meter set to impedance. The distributor is another potential problem that is less likely to prevent starting.
A vehicle that has a starter with enough power to turn the battery and spark but still does not start is not receiving enough fuel. The fuel pump or fuel injectors are likely causes of the problem. Check electrical connections to each of these devices. Use a fuel pressure gauge to check the pressure in the fuel line.
If the vehicle still does not start, the cause is more complex. It might involve a bad starter ring, failed fuel injectors or a problem with the Expedition's on-board computer.
