    I don't even care if you laugh, I did, afterwards

    You are now a senior citizen like myself. I crossed the 62 threshold last Sept. Getting old is hell......memory and eye sight are the first to go. I have tools in the tool box I didn't know I have & don't remember buying them either

    2003 Expedition Check Charge system still on after new alternator

    If anyone has the service manual for the 2003, the workshop section has a description of each of the three wires that connect to the alternator in the plug. I've misplaced my cd for that year but looked at the 2002 - same plug but different color wiring so there may be a difference between...

    Switches not working

    Hey New2Expeditions, you may want to check the date on threads before replying. This one has been inactive since 2016. Plus the OP disappeared in 2016.

    Charging system issue

    The 2003/2004 have known issues with the smart junction box and as you have found out are not completely swappable between years. One option is to compare the charging system wiring circuits between the 2 and modify as necessary.

    2003 EB stalling, 2wd, 5.4 - nightmare

    The box in question is called the "smart junction box". When Ford has an electrical change during a production run it is noted on the wiring diagrams as "early or late production". A few members have repaired their sjb for about $35, others have bought a new box for about 10x that.

    loss of power no one can tell me what's wrong

    Been a month since the op replied to this thread. It is probably another one where they go "poof" and disappear.

    Cranks but no start-fuel pump not coming on

    The pcm also grounds the injectors in order to run so it may be a harness or connector issue on the fuel pump circuit. You are also going to need the new pcm married to the instrument cluster by the dealer.

    Replacement A/C compressor help

    Most of us on here go with the parts list the vendors provide when looking up replacement items provided we enter the correct vehicle to start with. You don't need 10 members telling you the same thing.

    Truck won't start....

    What do you expect from a vehicle that is 15/16 years old? If that is the original pump you did well. Chalk it up to maintenance and move on with it. Not a good reason to sell it. Do you sell your vehicle when the tires are worn out?

    Truck won't start....

    If memory serves me correctly the 2003-2004 had fuel pump relay issues in the smart junction box. There is a thread on here by bedrck47 that walks you through the steps to jump the relay in the sjb.

    Replacement A/C compressor help

    Anytime you change the compressor it is a "given" that you also change the accumulator or drier. There is descant in them that has a life span. Plus it voids the warranty if you don't change them. Always buy new and avoid the rebuilt compressors - there usually isn't much of a savings. I've had...

    No Power

    If the problems started after the battery and starter replacement it is probably something they did. See the Electrical Section on the forum for trouble shooting "no starts" using voltage drop testing.

    Crank, no start

    They will have to "marry" the pcm to the instrument cluster then program keys. Usually not a cheap fix by any means. The keys need to be "different" and not copies of a single key. Another option would be to get an instrument cluster and pcm from a junk yard and have the keys programmed...

    Crank, no start

    The theft light will flash rapidly if there is an issue with the PATS, especially if it can't communicate with the pcm.

    Crank, no start

    The pcm will provide a ground for 2-3 seconds to the fuel pump circuit. If the engine isn't running in that time it will open the circuit. Bypassing the relay will enable the fuel pump and provide fuel to the injectors. If it still doesn't start then it may be a lack of spark/ignition.

    Crank, no start

    Welcome to the site. How did you check the fuses? Going off memory, the pcm has 3 fuses. Fuel pump relay: jump 30 to 87 in order to bypass the control circuit for that relay.

    Dead battery...2 times...

    Marlin charge the battery to 100% soc with one of the battery cables off. Wait @8-12hrs then read the battery voltage with a dmm. If it still drops to 12.3 then there is a short internally. If not you have a parasitic draw.

    Replace seized engine or replace truck? NEWBIE NEEDS HALP

    "I'm a musician, not a mechanic" You've answered your question. Brake jobs are one thing, engine swaps are a totally different beast. Toss in your location, time of year and it would be an uphill battle unless you have a heated garage. You Tube is good for basic info, what happens when you run...

    Charging System Service Soon

    Welcome to Ford electronics! The ecu has detected an issue with the charging system. That doesn't mean that there is a failure though. There is just something that is out of spec when it is checking the charging system. Plus it is under warranty, if you have a lemon law make sure you keep...

    Another dealer rip off story

    Guess this is one of the differences between generations. We ol'timers have tire plugging tools and plugs......

    Lean conditions on both banks. What could it be?

    I haven't read any article or emissions book that states a clogged cat will effect the air fuel ratio. Where are you getting your information from? Most cats go bad from raw fuel being dumped into them from misfires.
