Yes, you're correct, there should be voltage there at all times.
Post #18 shows a bronco fuse box from in the engine compartment. my chilton does not tell me what those fuses are for my truck or I just havent found the right page yet. If there is a fuse K on my truck for the same purpose that would completely explain all my problems. I replaced my ip a while back and it never started. I didn't think i had heard the click of the ip being turned on and thought it was a busted replacement. finally got time earlier to hook it up to a pump and gears to manually run it through and verified the pump does indeed push fuel.

If the fuse poped around the time or during the ip swap that would explain why it didnt start then and now. going to trudge out to the car and see if i can find some donar fuses or the tractor and see if i get it to start up that way.

I may try a manual gp run and see if that will do it 120 or so right now for a new relay and controller so on the fence if i would replace it.

I see what you're saying; you're right, there is a fuse. And I see what they did, they protected the circuit that energizes the power to the GP relay, the FSS, and the cold timing advance. You'd lose a lot blowing that fuse.

I'm not so sure this is in older rigs like mine, I do not have an underhood electrical distribution center, just the standard under dash fuse box.


Still, that would on work on actuating the relay, you should still have power to the lug on the hot side of that glow plug relay.

Glad you're making progress!

hi guys,

i finally got my ZD-9 s today and put them in the van.
too be sure everything works fine i checked the system as described by @FORDF250HDXLT.

Everything seems ok, voltages OK, the timings are between the given borders. Van fired up right away!

just one last question:
When i turn on the ignition as soon as the wait to start light comes up the solenoid or controller does a buzzing sound for the time of operation.
Is that normal?

update: just tried it again no more buzzing. strange...

an added note on clean the contacts, ITS NO JOKE. There is a wiring harness connector just behind/below that fuse box in chevy eaters post I had to clean that up before the GP/IP relays would work right. also after cleaning every single contact between the battery and the starter the starter did not heat up noticablly after a long turn where it did before I cleaned every single contact.

My main ride, for the highway, is a '93 IDI non turbo, that I have had since '99. It has made over 100 trips up and down the Baja over the years. Runs good with new injectors, almost like new, but this week I have been having some glow plug & controller issues.

Thanks for the great writeup, and all the glowplug 101..

In reference to this is a post that stays at the top of the board so it does not get burried. Kinda like a great big yellow stickies note that says Read First
