It wont start all in da suddent it just stop

SOURCE: Loud buzzing noise

From the sounds of it, it's simply your air ride's compressor. If you're not aware that your vehicle has air ride suspension, read up on the user's manual or look on the web. When you start your vehicle and shift into drive or reverse, your compressor should start (assuming no doors are ajar). The compressor than fills all four airbags in your vehicle to a factory-set height. These airbags provide a softer ride than the conventional shock/strut system seen in less expensive SUV's and trucks but are also more prone to problems and damage down the line. You can isolate the compressor as the sound by going to your truck, removing the left hand side panel and switching your air ride off. Your car's compressor then should not kick in at all. However, you should not operate your vehicle with this switch turned off. You should only use it as a diagnostic reference or anytime your car is towed, hoisted, or jacked up. Hope this helps.

He is absolutely correct and it is a recall on this vehicle.

If it starts, even after turning motor off (immediately) while the engine and ambient temperature are quite warm, it could be the starter relay (which is inexpensive), a starter- not inexpensive- a neutral-safety-switch, or an host of other electronic problems that Navigators/Expeditions are notorious for tormenting their owners.

The relay is what I finally was able to have fixed- and it was only $56 to have an independent shop do it.

Good Luck!

hi,

if its a 3.8 v6 then check the EGR valve. the egr valve will get a hole in it an cause a huge vacuumn leak, and cause that. untill you take it in you can plug the vacuumn hose that goes to the EGR valve on the intake manifold, fix it soon.
