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.
A trouble or error code of P1151 on a Ford Expedition indicates an overheated exhaust oxygen sensor. This may occur because of a problem in the sensor or a problem in another system that overheats the sensor.Full Answer >
Removing a fuel filter on a Ford Expedition requires the battery to be disconnected, the fuel pressure released and the vehicle safely raised from the ground. Once the vehicle is secured from the ground the filter can safely be changed.Full Answer >
A Ford gas gauge fails when there is either a shortened or opened wire in the electrical system. A shortened wire blows a fuse, while an opened wire doesn't allow any electrical current to reach the gas gauge.Full Answer >
While there are many different symptoms of transmission problems in a Ford Explorer, one frequently reported symptom is the illumination of the "check engine" light on the instrument panel. While the light says to check the engine, the sensors throughout the power-train constantly check the condition of the engine, transmission and, in some cases, the anti-lock brakes.Full Answer >
