2000 Ford Expedition Wont Start Again

Machine model: 2000 Ford Expedition 5.4L Triton V8

Symptom:

Cranks but won't first

A few years ago the battery was replaced in it later on sitting up maybe 5-6 years at the time. I figured it wasn't getting fuel so I knew the event was probably the fuel pump.

Also, thoroughly cleaned and degreased the fuel tank.

What I did:

I bought a noid lite gear up and a fuel pressure gauge to exam the fuel pressure and fuel injector electrical connections but they all checked out fine. Fuel pressure at the rail was around 40psi. All I tin think to practise next is replace all viii fuel injectors in case they are gummed upwards.

Update:

I figure it'due south getting spark since it does start when using starter spray. Information technology seems to be an outcome of non getting fuel so I think I'll but go ahead and change the injectors. This weekend I'll remove them and see what kind of condition they're in.

Update:

I took a chance and went alee and ordered fuel injectors for it and installed them on the twelfth. Only took about an hour to replace them and they were very gummed upward with the same gook from the fuel pump and fuel tank.

After I installed the new ones it fired right up. I spent this past weekend draining and flushing the cooling system and I also changed the oil. It's running pretty good so far with a little hesitation at times. I added some seafoam to the gas tank to help clean out the rest of that gook because I saw there was a fiddling left in the fuel rail subsequently installing the new injectors.

Update:

I did change the oil filter too during the oil change. Someone else mentioned to check the brakes likewise.The SES light is on just when I checked information technology it says something about Keep Live Retention as well depression or something. Comes on about 10 seconds after every starting time and my Foxwell NT520 won't automatically pull the VIN and identify the vehicle either. I have to manually select my vehicle when using it. I approximate I have to do a PCM reset???

Is there annihilation else recommend doing to it?

You should LOAD test bombardment and alternator as any weak / low cells can cause a multitude of sins . Also check ALL earths / grounds .Bank check this , might help , might not .

"Some of what has been posted is not entirely accurate and there is a much faster method to clear the KAM (Proceed Alive Retentiveness).
The KAM tin can be reset using a capable scan tool in a few seconds. If you don't take a capable scan tool disconnecting the PCM (figurer) for x seconds will also work. Another method is to remove the positive battery cable and connect a jumper to the positive battery cablevision end to ground for 10 seconds.
If yous leave the battery asunder for a long plenty period it volition reset the KAM provided the dorsum-upward power supply is discharged. The backup power supply is mainly used for the air bags, just information technology will feed other modules for a period of time as well.
Information technology should too be noted that someday y'all load a new tune into the PCM the KAM is reset also.
It commonly takes almost 50 to 100 miles for the PCM's adaptive strategy to relearn. When you 1st start the auto subsequently resetting the KAM you should let information technology idle a couple minutes with everything turned of in park/neutral. So plow the a/c on for a few mins, and later that put the vehicle in gear for a few mins if you lot've got an machine trans. When your done relearning the idle strategy, drive the vehicle like you normally would. I do not recommend driving information technology in a manner out of the ordinary at this fourth dimension. "

Add:How to Troubleshoot a Ford Trek That Won't Outset(this port from itstillruns.com)

When troubleshooting a Ford Expedition for a no-showtime condition, the starting time objective is to determine in which system the failure lies. Looking at the problem from a technician'due south signal of view is the nigh expeditious method. A technician will immediately go for the most common problems first. The possibilities are unlimited when taken into context–the electrical organisation, the ignition organization, fuel system, estimator or components within its sphere of influence (of which in that location are many), the security organization and a mechanical failure in the engine.

Step i

Check the starting circuit. The starter must engage the flexplate gears and rotate the engine in order for it to get-go. This happens when the fundamental is in the full, forwards start position. If no noise is emitted when the fundamental is in the start position, the problem area has been located. If this is not the example and the starter operates, the testing procedures for the starter circuit can exist ignored.

Step 2

Elevator the hood and inspect the battery for any irregularities such as corrosion, loose or broken terminals and repair equally necessary. If whatsoever of the problems to be covered are found defective, repair and retry the starter. Proceed only if the trouble has non been corrected.

Stride three

Cheque the battery voltage with the voltmeter. Connect the ruddy voltmeter pb to the positive terminal and the black pb to the negative final. The voltage should read 12.5 to 12.75. If the voltage is one or more than volts lower, the battery is discharged or has a bad cell. Charge the bombardment and retest. If the voltage rises to the appropriate numbers, try the starter once more past having a helper turn the key to beginning while you lot watch the voltmeter. If the engine starts or if it doesn't, the important thing is the reading on the voltmeter when the key is in offset. If the voltage drops to beneath 10.5 volts, the battery is bad and needs to be replaced. If the voltage does not driblet and the engine starts, check the voltmeter again. The voltage should now be 13.viii to 14.5 volts if the alternator is proficient. If the voltage is incorrect, replace the alternator. If the battery voltage is correct and the engine notwithstanding does non try to start, the starter circuit is at mistake.

Step 4

Cheque the fuse and the relay in the fuse relay box on the driver'south fenderwell. If the fuse and relay are OK, bank check the ability to the starter solenoid past connecting the voltmeter's black lead to a skillful ground and using the red lead to probe the terminal where the big diameter ruby wire is attached on the starter solenoid. If there is no voltage, the wire between the solenoid and battery is bad. If there is voltage, pull the small wire off the solenoid. Probe this wire connector as the helper turns the primal to start. If there is voltage, the starter is bad. If there is no voltage, the ignition switch is bad.

Footstep 5

Bank check to encounter if there is a computer organization failure by turning the key to the run position with the engine off. Plug the code scanner into the OBD port on the left underside of the steering cavalcade. Printing the key marked "Read" and the scanner will display any failure codes for the faults it has recognized. The code is a letter followed past four numbers. The letter designates the location and the numbers the error. Cross-reference the code with the accompanying code sail and a description of the error volition be presented. Correct the mistake and try over again.

Step 6

Bank check the fuel system. Open the fuel cap and have the helper cycle the key all the fashion on for three seconds and off for four seconds. If the fuel pump cannot be heard, try 1 more test for accuracy. Remove the air intake duct to the throttle body. Agree the throttle linkage open. Squirt a good shot of carburetor cleaner into the intake manifold and retry. If the engine starts and runs for a few seconds, the fuel pump has failed. If it still does not start, check the ignition.

Pull a spark plug wire off a spark plug. Insert the examination spark plug and lay it on the intake or block where it will be grounded. Take the helper try to start the engine and watch the spark plug. A skillful spark indicates a trouble internally in the engine. No spark means the ignition organisation is at mistake.
