Value estimate?

[rusty ol ranger]

I'm always looking at prices of these trucks... it really depends on your location. That truck may be worth $2k to $4500 depending on where you live.

Im in michigan. So finding one thats not rotted in half and of good driver/work truck quality is rare. Honestly itd even be an easy resto for someone. Hang some doors, weld the floorpans, find a good straight box, fix the oil leaks, and hit it with some paint itd be pretty mint.

Even a 2.9?

Oh wait, 2.9 is EFI, 400 is carb. Question withdrawn.

If youds asked me before the rusty 2.0 debacle, then yes i woulda picked the 2.9.

I still think your issue is something simple in the wiring. My experience with the 2.9s doing stupid stuff is that a damaged O2 sensor or a wiring issue are almost always the culprits.

Have you tried swapping the whole harness out of Rusty 1?

No.

That harness became a all you can eat buffet for mice.

But lemme ask you this...i know the negative battery cable, and little wire grounded to the core support is total junk. The big wire got cut half thru by the alternator pulley and the little wire has about 3 strands of good wire hooked to the terminal.

I noticed this about the time all this BS started. I bought a new cable months but aint installed it yet. It was still starting fine so i didnt worry to much.

But how much other shit grounds thru that?

That ground isn't important at all. Ford only put it there because they accidentally designed the truck with one too many holes and a supplier sent them extra bolts for free, so they figured "why not?".

That wire grounds the cab and pretty much everything in it. It's very important, fix it.

Only the entire electronics package for the PCM.

If you unplug that wire altogether the engine won't even run.

Shit.

Seriously?

If that 20 dollar 20 minute to change wire has been the problem this whole time im gonna eat a pile of dog turd.

WTF is the cable looking wire then that is down next to the ECM? I thought that was the ECM ground.

On the PCM you have two sets of ground. You have "ground" and you have "power ground".

The "power ground" is the little guy on the kick panel right next to the box. It is the ground for the power the PCM uses to turn itself on.

The "ground", up at the core support is the one it uses to reference all of the sensor signals, ground injectors, relays, etc.

I might have my locations backwards, but I have my functions correct, and both are very important to the engine running at all.

Guess ill move those to the top of the priorty list then.

Would that be why sometimes when doing a KOER test things would get wonky sometimes?

At first i blamed the tester, but it did it flawless everytime on my 460.

It could be, but it could also be because the early PCMs were just wonky, especially with code scanners. Your 460 may still be EEC-IV, but its years more advanced.
