Look in your owner's manual

NEXIQ 125032 USB Link Software Diesel Truck Diagnose Interface Use professional quality oil filters. While purchasing economy oil filters may save a few dollars, you will be greeted on cold starts by a rattling noise that continues until the engine reaches operating temperature. All oil filters are not made the same. If you were to dissect quality oil filters, such as a MotorCraft, Wix or the Napa Gold Line model, you would see an anti-flowback valve installed within the filter. The purpose of this valve is to keep the oil in the engine's top end after the engine is shut down. By doing so, the valve train is lubricated instantly at start up, instead of seconds later after the oil pump has circulated the oil from the oil pan to the top of the engine. Dissect a cheap oil filter and essentially what you will find is a filter medium akin to a coffee filter, wadded inside a tin can. If you notice the ticking sound on start up, make sure to change your oil as soon as possible and use a good-quality oil filter. Protect the engine with the factory-recommended-weight oil to keep valve ticking noises at bay. Your 5.4-liter left the factory with 5W-20 or 5W-30 semi-synthetic oil in the engine. Use of thicker oils, such as 10W-30 or 20W-50, no matter the climate, can overwork the engine's top end as it attempts to work with the thicker oil coursing through it. Once you have installed the thicker oil, you will most likely experience a ticking noise that does not dissipate when the engine reaches operating temperature. The longer the engine is operated with the wrong oil, the louder the noise will get. The synchronizer, which controls the timing for the top end, will ultimately become damaged and need to be replaced. As soon as you discover this ticking noise and know you have used the thicker oils, have the oil replaced immediately with the recommended weight.

Go under the car and have a helper hold the key in the start position while you probe the wire to the solenoid for 12 volts, also do a voltage test on the positive battery cable and inspect it at the battery for acid intrusion near the positive battery post clamp, if acid has gotten into the cable the outer insulation will appear swollen and the cable must be replaced, this is a common cause of no starts on Explorers.
