Question about 2001 Ford Expedition
I have a 2001 ford Expedition 5.7 . Last couple of days i have had to get a boost off from a friend cause my truck wont start. I thought the cold weather was effecting the battery, so i bought a new one but is still having the same problem. I have noticed that when i dont get it to turn on from a boost and let the engine warm up i can turn off the truck and i can turn it back up shortly. It does turn over just doesnt turn on. Please help. Thanks Gaby

You need to have the alternator checked. Sounds as if it has a bad diode or internal regulator.

SOURCE: 2000 Ford Expedition wont start
On the engine there is a tube that supplies fuel to the fuel injectors, on that tube there is a valve, like a metal tire valve, this is the fuel pressure test port, you will need a special guage to check the pressure that screws onto that valve, Kragen and other parts stores sell this test kit, it is very inexpensive, about $20.00, but cheaper than having a shop do it for you, if you do the test and you have no pressure while cranking the engine then your fuel pump is bad, the pump is in the gas tank, a big job and dangerous due to chance of fire if you are not cautious.

Sounds like the fan and temp gauge (located on the intake mainfold is screwing up) , if its head gaskets it would be smoking out the tail pipe. Have you added any antifreeze if so was it once a week if so make sure nothings leaking on the ground if there isn't then its your head gaskets that would be a first for a 4.6 which is a good motor and none I would on ever had bad heads. I would check the water pump fan first with truck off grap fan at 9 and 3 and see if it wobbels forward and backward if so it's the fan. I have come across alot of bad fans. Fan would cost $30 and up. Rate of difficulty 1-10 I give it a 4.

the air suspension system is failing,check the suspension switch located behind the passengers side kick panel to see if its on,check the fuses,worst case a hole in the lines to the air bags or bad compressor.about the sunroof-not sure

the expeditions are know for having injectors stick open and will flood the cylinder causing hydolock, when it does this again remove the spark plugs and have someone roll the engine over, if fuel comes out of one of the cylinders then that cylinders injector is at fault. the motor will turn over after it sits because all the fuel will eventually run past the piston rings.
