I had a issue today, my 84 BJ42 3B superglow didn't start. The EDIC would not move.
I recently added a wilson SW to my superglow (did the blk/yel and blk/red across the sw), this setup works great, my superglow was only applying the 12/8.5 V for 3-5 seconds, I thought with the warmer weather the smoke/chugging for 20 sec. would get better, not much. By giving it another 5 seconds, it starts clean.

My question is, does the superglow fire the EDIC?, could my SW be messing with it?
Some people say to disconnect the superglow, but I only use the SW when the truck is cold and would like to use the original most of time.

To get the truck started, I moved the lever by hand while some hit the key, it fired right off and started working. turned it off, restarts fine...hopefully good from here????
 
I don't see any wiring diagrams where the superglow somehow feeds the EDIC.

The EDIC relay has the following inputs:
  1. Oil pressure switch
  2. Always on power
  3. Ignition switch ON position
  4. Ignition swith START position
  5. Ground

Other than that, it has 4 wires that go to the EDIC motor. There may be one additional wire, labeled EX, but I have yet to find a diagram that explains where that might go, and my EDIC relay/motor setup does not have it connected to anything, and it works just fine.

I don't own anything with superglow, so I'm not positive about it, but I understand that when you hit the starter that the superglow system starts running its sequence, which is separate from the EDIC system.

If his truck starts when he manually puts the EDIC arm to run then would the ignition relay be faulty?

My brother and I are in the middle of chasing our BJ42 EDIC/FCR no start issue right now. Our truck's symptoms started out similar to your's. First start attempt, no movement of EDIC. Second attempt and the EDIC would motor and the truck would start.
Recently however, it will not operate at all.

Just found a wiring diagram on-line. Looks like the black/yellow wire from the start sw also has a feed to the glow plug control sw.

EDIC control relay, not sure where it is on a 40 series, it may be called an ignition relay, not sure. It is in the right side kick panel on a CAN spec 60 series, may also be called fuel control relay?? May even be the plug connected to the relay, mine was corroded, spent some quality time with a piece of emery cloth.
Just guessing, I currently don't have a diesel, but have a few in the past.
Also, have a look at this post

EDIC control relay is hanging off the pocket wall on the Cdn spec BJ42. Don't know about other country specs.

I know my EDIC relay and my grounds are good. I've a lazy fuel control motor. The motor was rebuilt a number of years ago. Theres a contact plate, and I have to get in and clean the plate and contacts once in a while. Access via the small bolts on the top plate where the fuel control rod pops on. One more place to look anyway, after you have eliminated the usual suspects.

You can start the vehicle without the relay or edic. I recently had my motor burn out and had a generous ih8member send me one of his.

I ran my truck without the edic or relay for a long time. All you have to do is just disconnect the edic lever, then pull back the IP lever back into start mode and start the truck. BTW, without it being pulled back to start it will be really difficult to start, but it will start. To shut off the engine, push the ip lever all the way forward.

With parts getting hard to find for these vehicles, it would not be a bad idea to put in a back up edic cable in-case the edic fails and put in a wilson switch in case the glow plug relay does not work.

Does your fuel control relay still click even when the motor is not moving?

The only problem with circumventing the EDIC syst is you'll no longer have low oil pressure shut down protection.:whoops:

When it acts up and I've no time to take it apart I've run with the arm off. Sometimes contact will sort itself out on the disc. Then relay will click through it's sequence to get where it should be in relation to the key position. I've also been able to complete the sequence by pulling or pushing the rod. I can't answer your question directly, as I don't have clear recall. And it's not a daily driver, having road insurance on it 3 months out of the year. I'll watch for it and post up, but it might be a while.

It's not a big job to take it apart; just time. If you take it apart to check the contact plate, take photos of the position of everything before you lift the arm and contact plate out.

Also, have you run a jumper cable from the EDIC motor to a good ground point to eliminate bad engine ground as the culprit?

We have tried grounding the FCR but haven't tried the motor. Great idea. We will try that next!

Thx
