County not firing

[Pedro500]

Merry Christmas everyone. Full disclosure I searched the forum before posting and went through a bunch of the suggestions but still stuck.

I have an '86 County, 4BD1. Has been running very strong for the five years I've owned it. However last week it wouldn't start. I noticed a springy "click" when turning on the ignition, it sounded slightly different to the usual solenoid style "clunk". It cranked over but wouldn't fire.

- Battery is brand new, it is cranking hard.
- It previously had an issue with sucking air through the old primer pump- I have replaced that with a new Bosch (12 months). I thought this might be the case again but fuel is getting at least to the fuel filter, as I can see it come out the bottom filter screw when I prime.
- The springy "click" appears to be the culprit but I can't figure out what it is, especially as it seems like I'm getting plenty of crank from the starter.

Any thoughts would be appreciated, hoping to get her back on the road for the holidays. Cheers.

First determine if it's lacking in spark or fuel.

It's got fuel at the injector pump. Not sure what you mean by lacking spark?

Sorry, I thought it was a 3.9.

No, Isuzu.

The fuel cut off is a motor thing mounted on the guard from memory. I think it's called an EDIC motor.
It turns an arm on the injection pump when you turn the ignition on or off.

I'm a bit rusty on the details, it's been a long time since I had my County.

That's were I'd start.

Cheers Tony. Will have a look.

As above.

One thing not clear is whether the motor is turning, but assuming it is, the EDIC device or its wiring will probably be the issue. An emergency fix is to replace it with a bowden cable to use as an engine stop. (Note that this is not legal, although this scheme was used on Series diesels.)

The EDIC lives in a plastic bag to the right of the brake pedal box. It does tend to stop working if the vehicle has a history of deep wading.

Thanks John and Tony, the EDIC was the culprit. I disconnected the cable and it started straight away.

I've jury rigged a manual engine stop so at least I can drive it over Christmas and have time to deal with the original fault.

Cheers!

...the EDIC was the culprit...

Don't know how available replacement EDIC units are. On recommendation from somewhere on AULRO I purchased an EDIC from Chop Hock Hong, Singapore...back in 2015...Auto-electrical Parts | Chop Hock Hong | Singapore (https://www.chh.com.sg/) I purchased the EDIC to replace the pull cable in anticipation this would be required to meet vehicle rego requirements on an engine swap. Don't know how this EDIC compares to the County unit.

KLR seem to have the goods Perentie Engine Stop Control Motor - BYG9369 (https://klr.com.au/fuel-system/perentie-engine-stop-control-motor/)

the EDIC motor, the exact one used on county/perenties are the same ones used in many shindaiwa generators round that 30kva - 100kva, from about 10 years ago, as they used the same isuzu engine.

I'd suggest if you remove it and find a local shindaiwa generator dealer they could likely help you. I'm no longer in that industry so I simply dont know now.

Thanks everyone. I was in touch with Chop Hock Hong, they were happy to send one over for 300SD plus 190SD postage...
I ended up having a look on AliBaba (yeah I know) and found one that looks the same, has the same part number. Paid $60, and it's just landed at my door less than a week after I paid for it.

If it only works for a week to get me through the pink slip, I'll take that. Will let you know how I go!
