I would scan it first, always a good place to start. That said it's common for 2003 and 2004 models to have the fuel pump relay burn/melt. It's behind the passenger front kick panel and could easily seem to be coming from the glove box.
Pull the kick plate trim and then the kick panel, pull...
Not sure what I was thinking the other day when I noted that the vibration was present to 80mph, maybe it should have been 70mph. Anyway, today I pushed full throttle from 0-70mph and couldn't feel it at all until I backed off. It's present from 32-74mph, really starts to go away about 70mph...
There are numerous potential causes of the Check Engine light coming on and the engine dying. Fuel pump, fuel pump relay, poor ground, a short in a wire somewhere come to mind. Best bet is to buy a code reader or get an adapter and ForScan and you'll be able to do quite a bit of...
What engine would be more reliable that would be a reasonably easy swap? Now if you're talking about going old school like a 351W or 460 in that case I would agree, but I'd be concerned about keeping it street legal. I couldn't get through VA state inspection with and old school engine, :-(.
This thread has some good info.

I have no help on the air shocks. Sounds like a good idea though.
Rear diff will be 75w-140 gear oil with a 4oz bottle of friction modifier for the limited slip if...
I'm thinking maybe you need to test the oil pressure sensor. It's pretty easy to do, it's a single wire sensor and the article below describes it fairly well. Access to the sensor might not be so easy though.

The Ranger trans pan gasket has been replaced, the trans cooler hoses were leaking so they were replaced and I ordered an entire gasket kit for the engine. My goodness I was shocked, the valve covers and/or intake are leaking oil and it's covered both side of the block, the oil pan is leaking...
The general consensus on the intake manifold is to reuse your factory manifold if it is not melted or cracked. Clean it well and inspect it well. Then get new Motorcraft gaskets for all you can. Based on what I have seen from others on here if mine was damaged I'd go see if I could find a...
I'll keep the fans and intake on my list. That list got a good bit longer recently. One of the list additions is a trans pan gasket on my sons Ranger. It's dripping on the cat so that is right at the top of the list and will replaced tomorrow night. Next up for the Expedition is to cut out...
The oil pump being mechanical it's unlikely it would fluctuate pressure from normal to zero. So I'd be looking at a sensor, wire or a connector. I would start with a scan for any codes that will likely provide some guidance.
The water pump has been replaced. I took the opportunity to flush the coolant out, it was on my list to do so now was the time. With the pump and thermostat out and then pulling the heater core hose from the intake it's pretty easy to get most of the coolant out of the block as well.
I...
Yep connector was gonna be my suggestion. Glad to see you figured it out.
Well done on the troubleshooting and thanks for sharing details start to finish.
It may not be what you're looking for, but I keep thinking a bed mat would be big and flexible enough that you could cut it to fit. It likely wouldn't look as nice as a custom molded piece though.
I have no idea, but I would go to a salvage yard and grab the brake lines. In fact if you had the fittings you could cut off the current connectors on your new lines and replace them with the factory fittings. You'd have to flare the lines again, but that's not too hard and you can rent a...
Yep, it's an SSV model, Special Service Vehicle. They have a different list of options and different standard features. As far as I know the Expeditions had the same drivetrain and suspension unlike come of the SSV model cars.
Another option for the rear may be to pick up 3rd row seats at a...
That does make a good case for reliability. It is something to seriously consider once I have my vibrations resolved, rusted rocker and 2 smaller rust issues resolved.
I am sitting here just laughing and thinking hell yeah. The smiles per gallon is so much more satisfying. My wife said the same exact thing after we put exhaust and suspension parts on her Monte Carlo.
I keep thinking about the e-fans due to the space it frees up. Despite the fact that I...
Something certainly sounds fishy about the stereo install.
Have you scanned or codes? There are codes that can be set for the Electronic Automatic Temperature Control module, since you have an EB model I assume it has EATC. My only other thought is to start testing wires, maybe start with a...
I wasn't able to touch the truck over the weekend. This evening I decided to just check the engine accessories again since I didn't have very long. I popped the belt off, it's certainly smoother without the belt on it and low and behold my water pump is weeping a bit. I found a bit of coolant...
I think you'll need to get it up on jackstands with the front wheels chocked to keep it from moving, start the engine, put it in gear and get under there to find it. A cheap mechanics stethoscope can help tremendously.

BTW, it can...
Ahh yes, I misunderstood what you were doing with the battery leads. Just connecting the wires pos and neg to together I understand. Connecting the ground lead to the pos battery post though didn't make sense to me.
Now that you mention the grounds, that I often seem to forget about, that...
