2003 overheating?
Sounds exactly like what I experience with a bad head gasket. If this occurs on first startup, what I found was that the coolant would leak into the cylinder when the engine cooled down overnight. This set an air bubble in the hoses that lead to the heater core which prevents flow. The are above...- BlackCoffee

Driver front caliper locking up.
I agree, I have been running with the track light for two years, it should not be causing a problem. It should be out of the circuit when it throws a fault code. The stability control also only activates intermittently. If the caliper is locked while driving straight, look elsewhere. Did you...- BlackCoffee

2003 Ford Expedition 5.4 EB 200K miles. strong crank with no start. New fuel pump, maybe a ground ?
It could be a few different causes. Before jumping at the fuel pump, I would put a fuel pressure gauge on the fuel rail and see what you get. 35-50 PSI is the working range. Pressure gauges are cheap and hooking to the Schrader valve is easy. If it cranks, you are getting power to the starter...- BlackCoffee

Can't Get Rid of Engine Roughness - Ideas?
The coil is fired by the computer grounding the coil. Check the resistance between the coil and the computer. Also check to see you have the correct voltage at the coil connection. A bad coil will take out the circuit in the computer.- BlackCoffee

The vacuum line is not connected to anything
I don't think this is the vent for the 4x4 hubs. That is usually down by the shock column, hard to see, and is turned down to prevent water from entering (like on a ship). The line you are looking at should have a T on top. On one side is goes behind the battery to the air box. The other side...- BlackCoffee

Opinions Please 2006 Expedition Limited
One more heads up. These are easy to change, so they can be replaced if there is a problem. Give a good check on the steering components and Upper/lower ball joints. Also, make sure the boots for the half axles are still in good shape. No problem, I did mine at $260K on my 2003 EB and it was...- BlackCoffee

Opinions Please 2006 Expedition Limited
I would agree with agree with both Gary and Rip. First, electronics. They may work now and well into the future. However, that is the downfall. Most of the electronics don't generate enough interest for aftermarket suppliers to build replacements and Ford will purge their stock inventory after...- BlackCoffee

Various module communication issues and J2534 adapter suggestion

Timing Chains
I got a Melling kit about 3 years ago which had the chains, crank sprocket, guides, and tensioner. The modular engines had about a year where the sprockets were actually part of the camshaft as an assembly. Check yours before you invest in Cam Sprockets. I had that on by 5.4L. Since I needed new...- BlackCoffee

No Crank-Buzzing from CJB
Latest update. Got the PCM installed. Had the new keys cut by my neighbor. (handy to know a locksmith and FFL dealer). Everything works great. Don't know if it was just the CJB or both, but I didn't want to take a chance since the scanner would not talk with the PCM. Another problem solved and...- BlackCoffee

No Crank-Buzzing from CJB
I think you may be correct. This is the first time I have not been able to communicate with the PCM. I did think that might be connected to a short in the fuse box. I bought the Expedition in November 2002, checked the VIN and your link should work. Got a little time before the PCM shows up so I...- BlackCoffee

OK, made it to pinpoint A10 and have no voltage on the starter relay. Next step is section 419-01 Passive Theft System Concern. That doesn't sound promising. Throwing my first part at the problem.

No Crank-Buzzing from CJB
So, could not start this morning. There is no crank and it does not sound like the starter solenoid is engaging. The most obvious diagnostic is a buzzing sound from the Central Junction Box (CJB) by the PAX kick panel. The buzzing is associated with turning the key to the on position. It is not...- BlackCoffee

Learning the Ropes with The 5.4 EB 2nd gen
Rebuilding the transfer case is pretty easy. Make sure your rebuild kit has the front seal between for the drive shaft to the front differentials. It develops leaks. Also, check all the vacuum lines and check valves leading to the front hubs to make sure they are intake. There is a vent riser...- BlackCoffee

The fuel pump relays on the back side of the fuse panel circuit board are a known problem. Depending on how comfortable you are with soldering in the relay chip, a number of YouTube video's show the repair. If you are not comfortable with that, you can replace the panel. I did the former.

Did you need to order camshafts and sprockets or were they included in the kit? In 2019 I had to replace my camshafts for the same engine and it was a little bit of a nightmare.

Did you check the voltage coming out of the new alternator? Also, check the tensioner and serpentine belt to make sure it is not slipping. Does it occur during a turn a turn or when the A/C kicks on? If you belt tension is down, the additional load may cause the belt to slip.- BlackCoffee
