Hello and thank you for your question, My name is ***** ***** I will assist you today.
Your 2007 Expedition doe not use a driver module, so you will not find it on the frame the fuel pump is controlled by the PCM (computer) through the fuel pump relay . See the wiring diagram in the link below, copy and paste the link to your browser to open and view the link. I would start with checking your fuel pressure to be sure its with in specs.

Unfortunately I am unable to call you at this time, do you have more questions and or need more help?
Customer: replied 1 year ago.
Yes Vehicle is a SSV (Police) .... It currently has no power, no longer shifts hard and fast like it used to..... Current mechanic has checked and verified No plugged converter, fuel pressure good, new plugs & coil paks with boots, new fuel filter, no stored codes or check engine light.... Starts and idles fine.... Maf and Throttle body replaced also...... Vehicle has had all maint service performed. Is it possible that the computer has lost its shift point information. Occasionly if you dont get the gear selector exactly on "D" with it illuminated it starts driving very sluggish at about 20mph..... Do you think it would be worth going to the dealer and having them re-program the computer ????

Currently has 145K mileage
Expert:  Ron replied 1 year ago.
With the amount of miles you have on the engine has the exhaust ever been checked to make sure the converters are not restricted, if they are they will affect power as well as the shift points.
Customer: replied 1 year ago.
Yes, exhaust was pulled today and verified all back pressures are within spec...
Expert:  Ron replied 1 year ago.
So I assume the computer is not setting any fault codes, correct.
Customer: replied 1 year ago.
correct.... Did you see my orignal answer to you unable to phone call message... I detailed everything to date
Expert:  Ron replied 1 year ago.
I see it now, sorry for the double questions, in most cases if the computer sees any type of fault it will set and store a fault code and or codes, with everything you have already tried, it is possible the problem is with the transmission and or the programming, it may be a worthwhile shot to go ahead and have it updated with the latest software and see if it resolves the problem.

One last question..... What if it got some E85 as opposed to the 87 octane it normally gets... This first became noticeable at a Kroger station when I filled the tank.... What if they put the wrong fuel into the storage tank ???
Expert:  Ron replied 1 year ago.
You really should not have notice any major difference in the way it ran with one load of E85 fuel and it sure would not affect the transmission shift point at all.
