The 128k truck is slow at starting and at times does not with only clicking sound. Battery is at 12v and with alternator 14v, so that looks good. Is there anything else I might be missing before I start with the starter? Is there a walkthrough(pics, howto, etc) on here or net? Where is the starter located? Thanks in advance.

the started is located under the engine near the flywheel housing
I would start by checking all of the wiring at the battery and at the starter for any signs of looseness, corrosion etc.
Also keep in mind that the starter relay is part of the circuit board inside of the fuse block. (smart Junction box). There have been many issues with relays going bad on the circuit board and normally are not user replaceable. Not saying that is your problem but its possible
Check the wiring as I mentioned first.

if you need to you can pull the fuse block and disassemble it to check the circuit board for burn spots
View the attached links These may give you some ideas as to what to look for on the circuit board.

You may see reference to a fuel pump drivers module Don't worry the 03 expy's don't have that module as it was only in the 05 and 06 expeditions

Connections can look good but are high in resistance. Better to let the tools tell you what condition they are in.
See the link in the electrical section on voltage drop testing if you are unsuccessful in getting it to start.

I went under to look at the starter and the red cap was still on..no corrosion, connections clean and tight. I decided to take the battery for a full check and came about bad..I guess it was the internal CCAs?..got a new free replacement battery (which had warranty till March 2015) and PRESTO! Thanks everyone.
