Truck has been dying for the last several years. Either when it get to hot out side or it just needs to take a little break. Then want start until it feels like it should. Whether its running or when I start it up. Checked the fuel pump, changed the spark plugs,wires, battery cables, everything but, ignition module. Which I'm doing tomorrow.

Major problem regarding ignition system: first problem began about 6 months ago. On an intermittent basis, unable to restart the engine after letting it sit for approximately 5 or 10 minutes. Repeated attempts in succession fail to start the engine but have found that if I give it a couple of minutes before trying to crank it up again it will usually start. Seems to happen only after short trips, less than 10-15 miles. Replaced the fuel circuit relay 2 months ago, had only one reoccurrence a week later. Now for the past 2 months there is a much worse and potentially dangerous problem. The engine shuts off randomly usually while driving between 55-70 MPH. No sputters, no backfires, no indications that the engine has shut off other than the instrument panel dims and the gauges stop reading. The engine won't restart until after a few minutes have passed before trying to crank it again. This is very dangerous as it usually happens while traveling 70 MPH. Dealership is unable to duplicate the problem, no error codes are reporting. Fuel pump: fuel gauge not working for several years, hole in float per dealership, so entire fuel pump replaced at my cost. Fuel gauge appeared to be working correctly; however, on an intermittent basis once the tank got down to 1/4 full the gauge would start off at 1/4 but then after driving for 5 or 10 mins. The gauge would go all the way to full. After a few months of working sporadically, it is now consistently going to full everytime the tank gets down to 1/4. Dealership diagnosed the fuel sending unit as defective but will not cover under the warranty because even though it has only been 6 mos. , it is approx. 2000 miles over the warranty limit of 12,000 miles/12 months. I would have to pay the same $340.00 parts & labor as 6 months ago. I feel this is unfair so declined the work, now being charged $67.00 diagnostic fee! Cruise control: the cruise control won't engage on an intermittent basis, dealership unable to duplicate.

Vehicle is experiencing stalling problems, the ignition switch, steering column, fuel pump, and the fuel pump relay have all been replaced but have not corrected the problem, dealer can not find a problem, this could be an electrical failure.

Vehicle would intermittently fail to start. Problem appeared aggravated by warm weather and the completion of a short run. Subsequent diagnosis by listed dealer blamed fuel pump, although a second opinion disagreed. After fuel pump replacement problem con

Explorer engine light comes on after combination of 1) driving on highway for approx. 1 hr and 2) have to climb a large hill...approx. 5 miles at 60 MPH. Truck stutters and bucks while cruising at 55-66mph when this happens. Truck was diagnosed approx. 10 times. I have all documentation for trying to resolve problem. Truck has shut down completely during one of these episodes losing power to steering and braking. As a parent of two small children I'm even more concerned. Dealership tried replacing fuel pump(2x), tp sensor, potentiometer with no fix. Dealership said it could be oxygen sensor, mass/map sensor, throttle control at one point but later changed mind. I know of one other explorer with similar problem. I hope this adds to your list. Please let me know if you have any information.
