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.

Set your idle speed to mfg recomindation if that doesnt help check the dash pot that is what keeps the engine from stalling at sudden speed reduction

Check all of your vacume lines. If it isn't a vacume line it is most likely the O2 sensor.

SOURCE: P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L

Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)

Code 1131= upstream; bank 1..sensor 1
Code 1151= upstream; bank 2..sensor 1
Code P0136 (generic code) bank 1..sensor 2 (questionable)

I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea.
Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.


Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read
open or a high resistance run two straps from eng. to body...and body to neg.batt. post.

You should check your blend door, go to the center of your dash look down towards the floor right at the bottom on the hump (tunnel area) you will see a black or same as interior color, cover it has small slits cut in it, it is held in by two expanding type plastic bolts, they do not unscrew, just pull them out, one on each side. Once removed locate the white small box with a wiring harness connected to it, a little to the right hand side. This is the stepping motor that controls the blend door. Remove the stepping motor, and reconnect the harness, look at the motor drive unit and operate the heater control knob, does the motor turn, if it does then use a mirror and look at the drive end of the blend door itself, it is probably broken. If the door is broken, this repair just got difficult, the entire dash will have to be removed to access the environmental station, once accessed there are about 10 screws that hold the top cover on the enviromental station, undo these screws and remove the top cover, then you can remove and replace the blend door. If you are not comfortable with this difficultly level in repair I suggest you seek out your favorite local shop. removing the dash is not easy, there are alot of screws, some in very difficult places to reach. Testing the motor is easy. I hope this helps, let me know.

I need to know how to set the idle speed on a 2000 expedition

2003 Ford Expedition XLT acts like it is starving for fuel. It starts up just fine but once going down the road it then hesitates and wants to bogg down. It has a really hard time on an incline. What could...


You need to install new spark plugs every 70,000 miles

If that was done, then you have a worn out TPS Sensor,
and possibly a bad COP Igniton Coil as well

You will get 1 or 2 coils a year go bad

If it is just on hills, when you have a high vacuum load,
then check out the EGR Valve

How would a 2006 ford expedition run with bad gas in it


It could consist of skipping, engine cutting off or hesitates from starting, idling . Bad gas gives numerous signs, the best way I have found to deal with this is, Buy a octane booster 104, go to the gas station and put a couple of gallons of high premium in to tank to disperse the water in the gas. They also make a liquid to take water out of gas which also goes into the tank.

I have a 2000 ford expedition. Out of the blue it started sputtering and shaking when I accelerate. Vehicle has144,000 miles.


Sounds like one of the coil over plugs have gone bad. this will cause mis-fire which causes your car to sputter, skip, and shake. It can be changed easily when finding out which one it is. But rather expensive for a simple part $40+ each.

The TPS sensor (or Throttle Position Sensor) is bad locate it and replace, it is located where the rubber air intake hose meets the intake manual, look for a wireand plug, also to make sure it is this sensor bring the truck to an Auto Zone and have them read any stored trouble codes for free this should confirm the faulty TPS.

Skips when going up hill(1999 ford expedition)


can be a number of things. if its only when going up hill may be a transmission or rear end problem.
if the problem is also in acceleration or kind of a bogging down it may be a firing problem like fuel injectors, plugs, wires, coil/distributor and rotor problem

ETC


You need to change the thermostat, it must be stuck open and the computer thinks the engine is always cold, hence the fast idle and smoke.
