Keep Blowing 20amp Maxi Fuse
#16
All fuseable links that I can see look fine. There is a single pole connector that plugs into the bottom of the fuel filter. Looks to me like it's a ground. Comes around with the fuel heater plug and the Water in Fuel sensor plug. I'll toss up some photos when I get home. The shop Internet service leaves much to be desired...

Yeah I would say most likely.Either way,if you left them unhooked and tested everything else and the fuse held,your good besides those.If you had them hooked it doesn't matter as the engine was cold and no power,so your still pointed to one of them since the rest wouldn't be the problem or the fuse would of blew...........and I no doubt could of worded that much better lol.

Well, we'll see. Batteries were drained down from previous starting attempts, so not enough juice to get it going. The longer the truck sits, the harder and harder it is to start. If driven daily it doesn't fuss.
The truck itself is a bit of a basketcase, and has been worked hard and hardly cared for; if it were mine, I'd give it the love and care (money) it needs to be where it should be.
Just look at this CDR valve...
That's a random hardware store 90° fitting.
Also discovered this:
That's the harness going up into the power distribution box, it appears.
Here are photos for the aforementioned filter plug:

That bottom plug has been "replaced" at some point, because I can see the heat shrink tubing and that certainly doesn't look factory. The crimping job on that connector is also horrendous.
Need to find a way to address that degrading shielding going into the distribution box. Does Ford still carry this kind of wiring? I've no quarrels with rewiring the distribution box. Odd to me that the wiring on that side of the plug has cracked the way it has, as there's no reason to believe there's excessive heat around there, and the side of the plug running all across the motor seems fine.
There is diesel, oil, grime, and who knows what else all over this thing though, so there's no telling what all could have contributed to the degradation. Were this actually my truck, I'd be giving it a thorough cleaning, but my task was just clutch replacement.
It's my dad's birthday today, so I'm not sure if I'll make it out to the shop today with the charger to attempt to get it going, but if I do I will report my results.

Little bit of an update; fuse has not blown on starting attempts since I've disconnected the fuel heater and water in fuel plugs.
Now the truck will not fire up at all. I've cracked each fuel line and I get fuel to each, and I also tested the movement of the solenoids on the IP itself. They click as though they move as they should.
Judging by the fact that the GPR clicks about a million times (the old one did this too, this is the new unit), I'm almost positive one or more of the plugs have given up the ghost. The glow plug harness is trashed anyhow.
I will get fresh plugs from the dealer, and see if I can get the harness as well.

I can order them all from Amazon for roughly $9.56 and have them here by Friday; not sure how quickly RockAuto can get them to me.
Looking for the glow plug harness, it seems they're $100+ or more, so I'll just make my own using the write-up in this section.

Got the new plugs in today! Had to purge air from the fuel lines as I believe it was last run on the empty tank, but started up beautifully. No more relay clicking a million times.
I've got to order some fusible link online (14 and 10 gauge) because no local store seems to carry them anymore in-store. I'll build a fresh harness once I have the materials.

Hmm, then perhaps you can point me in the right direction on something else. The truck has been hard to cold start after sitting even just one night for the last decade; have to hold the throttle for about 30 seconds before it'll continue on its own.
This is even after fresh glow plugs (which by the way, the truck starts fantastic without hesitation after the first cold start of the day), after which starting the truck for the rest of the day is no issue.
I drove it about 50 miles today running a few errands with it to stretch its legs and it drives just fine and motors along ready to go on. Since I've taken on the maintenance of this truck, I'd like to solve the little things here and there to have a more reliable truck for my elder friend who owns it. This will eventually include replacing/building a new tach sensor (I've seen the GM part write-up versus using a factory part, not decided yet) and a few cosmetic issues.

the hard start may be air intrusion. if you park the truck engine sitting downhill, it starts rite up, but if you park it engine sitting uphill it is hard to start rite?
park engine pointing uphill. after sitting overnight, or better yet two days, remove the fuel filter.
my bet is it will be half empty.
this is a sign of air intrusion. this usually happens when the return line cap o rings let air past into the return lines, which then lets the fuel filter drain back to the fuel tank.
air molecules are smaller than fuel, so you can have an air leak without seeing a fuel leak.

I've not tried parking facing downhill, but it's worth a try to test out that theory, I don't have a drive at the shop that slopes down far enough, so I may need to leave my truck at the shop and drive this one home tomorrow as my driveway has a slope.
I'll check out the o-rings as well and likely replace them just to do it.
