Ignition/ glowplug relay problem

G'day steve whats an edic motor?, the ignition /starter diagram that i'm looking at doesn't show an edic motor just the ignition, per heat timer, 2 glow plug relays, a resistor and a current sensor, and a water temp sensor(which i just had replaced due to a cracked thread, i think this could also be a likely problem)

The Edic motor is the little motor that opens the fuel pump via a rod about 200 mm long, its a small box with a swing arm on it as you turn the key it swings and opens the fuel pump.

Cheers Steve.

This will NOT remove engine power as the OP mentioned.

Cheers peter i will give that a go sounds like a fairly simple job is iteasy to get to and what is an EDIC?

I drive an '89 diesel troopy and have a good idea what the problem is.
If you DO lose power during the 'clicks its the oil pressure sensor which in turn controls the coil of the edic motor (actuator is a better term - it actuates the rack of the injector pump).

I used that function deliberately while the 2H motor was still under the bonnet of my trropy. Fitted a concealed switch that broke the connection to the oil pressure sensor. The effect of this was that the motor would start and run for a few seconds and then 'click' and stop. One could restart it and the above would repeat at nauseum.
Figured that any thief would give up by then and and go for an easier drivable troopy.

So, do check the oil pressure sensor, its on the driver side of the engine, near the fire wall, just above the EDIC motor.
Check the wiring to it, it may be intermittent and DO check your oil level - it may be too low or the oil pump not working properly.

EDIC stands for Electronic Diesel Injection Control.
Back years ago diesels had a cable that was used to control the injection pump, it was normally in the run position and to stop the engine you pulled the cable to put the injection pump in the stop position.
Then as things progressed to become more complicated they developed the EDIC system which as has been said is an electric motor which moves a rod to change the position acvcording to the ignition key position.
The reason for the box of electronics is the need to put the injection pump in a timing advance position for cold starts,stop the engine if there is no oil pressure and on later engines an idle up position for aircon etc.
On your 2H engine there is a second oil pressure switch which stops the engine if there is no oil pressure. That is because the 2H will actually run backwards if it is stalled especially when they get older. The oil pressure switch location has already been given above.

Thanks for the info guys, what i found was a fuel control unit in the passenger kick panel, checked unit and connections, no water in unit checked wiring to oil pressure switch and cleaned connection.

Had no click sound while i let the motor run for 20min lets hope its just loose connections.

Whilst we're talking about oil pressure the guage on the dash drops to low when i have driven the car at 90-100k's for extended periods what are your thoughts on this.

Thanks again i was completely in the wrong area when i thought glow plugs.

Dirty oil and tired engine ;-))

The motor is a reco only 35-40K old and i always change the oil, guess i was hoping for more loose connections.

Well i will be up in your neck of the woods soon, i hope it was just a loose/dirty connection, and problem is solved.
Send us a MM if you remember.

Regards...Stephen.

Thats kind of freaky Wayne my too happened on the Australia day weekend. The motor is a 2H, and no the electrical drain on the system was minor..
