The 2003 Expedition smart junction box was formerly called a GEM module in previous years. It has relays that control your keyless entry codes, the relays that control the dome lights and the delayed radio shutoff as well as other functions.On a 2003 Expedition, the sjb (smart junction box) is located on the inside passenger's side kick panel below the glove box. It is most easily accessed by opening the glove box and squezzing the limiting tabs on each side so the glove box can open fully and tilt forward. It is approximately 6" long by 4" tall and about 1 3/4" thick. The part number on the label will be 2L1T-15K602-AN or similar for 2003 Expeditions.

Sounds like a tune up is due.

Hi Antonio you can buy a top up can in place that sells parts. Simply attach the fitting on the can to the air con line with the engine running and the air on on full some cans have a gauge on them so you will know when it's charged. If the system has been opened and needs s fill you will need to go to a workshop or an aircon specialist. The system will need to be vacuumed to remove air from the pipes to prevent hot spots and then filled. Regards Jkm...

fuel filter or fuel pump

Spark plug boot puller tool?

I'd be looking at the condition of the battery first.Have you tried using jumpers to see if you can get it started?Tried disconnecting the battery and leaving it on a charger overnight? Cleaned the terminals and battery posts, cable connections?Lets try that and then see what happens.Cheerfuls!

What's up ! your fuel pump fuse is in the central junction box , but you also have a fuel pump relay , a Inertia fuel cut out switch .The central junction box is located -

under dash panel, RH side fuse F1.34 20amp fuel pump

have you checked your tranny levels if the oil is low when it warms up the torque converter will slip but as soon as you put it in reverse there will be enough oil in the finns to move you backwards .

Go buy the chiltons manual. There will be a chapter on this

Go to autozone and buy the repair manual. Look at it there to make sure it has the diagrams to fix.

Maybe a bad fuel pump or clogged fuel filter. Obviously if the engine is crankiing a no start it is not getting fuel. Additionally if you have bad spark plugs then you would also have same problem. Start with the easy thing first. Fuel filter then fuel pump

many possibilities, but if it runs well otherwise, check for bad cat converter.

When you changed the fuel pump did you change the fuel filter? I changed mine in my expedition 3 months ago and also changed the filter. Reason to change is because a fuel pump usually fails because of a semi clogged filter. The pump has to pump a lot harder thus it burns out. First i would check to see if pump is running. Have someone turn the key on and listen with the gas cap off. If you hear the pump engage then it may be a clogged filter. If you dont hear the pump then it maybe your pump reset. My pump reset is located on the passenger side front seat just in front of the door. Plastic shield must be taken off. There is a red button that you need to depress to re engage the pump circuit. Once you depress then it should start. Check your manual for pump reset location. Good luck

How about the battery? Is it good? Or ignition switch?

Check ignition switch the electrical wires
