Hi

My 2h HJ60 wont turn off on the key, whats the likely causes/fixes please?

have my vehicle safety test today and guess they wont like that !!!

I'm looking near the ebdic and cant see any wires or vacuum pipes to check?

Very likely the edic relay. It rests in the passenger kick panel.
A pretty common thing to fail, search here on mud.
You can try opening it up and cleaning the contact points.

Next, you can rig a choke cable to the lever on the fuel pump, pull it and the lever goes back and stops the engine.
 
Thanks, I checked the EDIC motor as the manual and thats OK. I'm getting negative low 12v on the Motor wire to the motor. Is that right?

I don't have any experience with the diesel you have, but I had a 1985 Mercedes 300TD with the OM617 5 cylinder diesel once that had the same problem. It actually had a lever near the throttle under the hood that had a big red sticker that said STOP on it. It was actually in the owners manual and said if the car won't turn off, pop the hood and press the STOP lever! PO had a cable rigged from that lever to inside the cabin. If I remember correctly, it was a broken or cracked vacuum line that was the problem.
 
First determine if your EDIC combo ( relay and motor ) are working .. ( through key position, EDIC arm movement ) then move on or post here for more diagnosis ..
 
Ok im still struggling with this. I took the motor off and checjed it on a battery and with a volt meter and its ok. I opened up the relay in the footwell and its all clean inside. Cleaned up its mount to the body, and cleaned the chassis to gearbox earth. Also have two new batteries on now. Still not working. is there anyyhing else ?
 
Do you have normal movement on the EDIC rod, going from the servo to the injection pump, when you cycle the key between on/start/off?
I seem to remember the arm on the pump is like this:
Arm back towards firewall= start
Arm in the middle= run.
Arm towards front= stop.

On that arm you can push it forward to stop, right?
The rod is connected at both ends?
Does the rod have that dampner/spring thingy?
(I've seen some create their own rod)

It would be easier to diagnose this if you add photos or a video.


so a 2H doesn't have a butterfly/choke to shut it off? like a 12HT

I've only seen fuel cutoff on the 2H engine, no vacuum butterfly shutoff.
 
Push forward on arm on EDIC. Should turn it off as stated above.

I had the opposite problem with the relay kicking on and off every 10-15 seconds. Misery.

Removed the arm on the EDIC and worked fine. When I wanted to stop, I put the arm back on and turned truck off normally.
 
Thanks.if i push the arm forward the engine stops.

the arm on the motor is not moving at all

.i took the motor off tested on a battery, its fine, does what its supposed to.

I opened the relay (in the foot well ) its clean, contacts are fine.

I need some more pointers re the relay maybe. Does anyone have a test procedure please.
 
Did you check if the relay really works? Does it give 12v (or 24v) towards the motor?
And in the engine compartment, does this 12v (or 24v) reach the right contacts on the electric motor?

So have someone turn the key (to off), and see if you get power on the connector of the electric motor.

OPERATIONAL CHECK

STARTING OVERINJECTION

When the starter is turned, the injection pump lever should move to the overinjection position. ,

AFTER STARTING (DRIVE POSITION)

After starting the engine, the fuel control motor lever and also the injection pump lever should be positioned between the two marks.

ENGINE STOPPING ACTION

When the starter switch is turned to "LOCK", the injection pump lever should move to the stop position and the engine should stop.

REVERSE ROTATION PREVENTION

Start the engine, and ground the oil pressure switch connector.

Then, the injection pump lever should move to the stop position and the engine should stop.

FUEL CONTROL MOTOR

REMOVAL

Remove connecting rod (1) and fuel control motor (2).

1853_21_526.jpg

INSPECTION

Measure resistance between "M" and "BM' terminals.

Resistance 12V type 24V type

1853_21_527.jpg

Fuel control motor lever should be positioned between the two marks.

INSTALLATION

jx 1. Install the motor and connecting rod in reverse order of removal.

Fuel control motor lever should be positioned between the two marks.

FUEL CONTROL RELAY

INSPECTION

1. Measure the resistance between terminals.

Resistance

ST-E, 12V type About 40 £2 24V type About 65 H

2. Apply positive voltage from battery to "ST" and "IG" terminals, and negative voltage to "E" terminal. Measure the resistance between terminals.

Resistance

3. Applying voltage as mentioned above, connect tester probes to "D" and "M" terminals. Cut the voltage for "ST" terminal.

Then, the reading of the circuit tester should continue at 0£2 for about 8 seconds.
