Expedition Not turning on....

[05_Expedition]

Hi guys new to the forum here and new to Ford. I have an 05 Expedition that fell in love with. Yesterday I drove it fine during the morning and when I was getting ready to go home it turned on but kinda odd. So I turned it off and when I tried to turn it back on I got nothing. The motor turns but it aint turning on. Hooked the comp on and gave me a whole bunch of TPS codes. So I switched the TPS and still got nothing, thought it was cuz the floater was stuck put 3 gallons of fuel anf nothing again. I put some fuel in the throttle body and nothing either. I'm running out of ideas as to what it may be anyone out there with idears I would greatly appreciate it.

A gas engine needs 3 things to run - air/fuel, compression and ignition.
Since you drove it earlier in the day I would rule out loosing all compression.
Next is fuel - do you hear the fuel pump running with the key in run position? It runs for 2-3 seconds.
Ignition - theft light flashing quickly?

Yup I got fuel, fuel pump turns on. Right now all of a sudden my throttle body started clicking. Whenever I disconnect it the motor turns, now whenever its connected the I turn the key and get nothing....im getting lost on this thing.

What are the active codes?
You may have fuel, only way to verify is to read cranking fuel pressure.
I had a Fiero that wouldn't run but the pump would run. Hmmm. No fuel at the injectors. Dropped the tank and found a rubber hose had let go. Pump worked fine except for that.
You probably do have fuel but if you could verify then you can eliminate that as a cause.

Are the 05's drive by wire?

 

[05_Expedition]

They all are saying the TPS and forced idle. I added more fuel just in the case that the floater got stuck and wasnt reading correctly. No its not by wire its all electronic.

I even added fuel directly to the throttle body and nothing. It looks like theres no spark or theirs a ground that may have gotten disconnected. But if my throttle body is clicking like that im not 100% sure what it may be. The way it happened just doesnt make sense.

Well after working on my Expy trying to figure out why it decided to just stop running. My throttle body motor when KEY ON ticks like crazy. And wjeb I turn the key I get no response. Now when I disconnect the throttle body motor the engine cranks, which is extremely odd. I'm in a mess of a confusion, I still dont understand why it just stopped running without giving a warning or anything like that. Today im going to try and see if I habe spark and then see whats going on with the throttle body motor. If anyone has come upon this before any help would be appreciated.

Have you tried pulling codes from the computer? What all have you replaced so far?

 

[05_Expedition]

Codes gave me nothing but TPS which I replaced but still nothing.

I know this sounds dumb.. Is the Battery good?

 

[05_Expedition]

The battery is good, probably draining now from attempting to start it but the battery is good. I think there might be a short at this point

What makes you think there is a short?

Check out the following link. I think your going to need a good scanner to find out what is going on.
