Hi,

I had a question a little while ago about glow-plug woes in a late HJ60 that had come down from the tropics to chilly Melb and didn't want to play anymore. It tuned out not to be the plugs after all (although I bet the thorough clean I gave all the contact areas wouldn't have hurt).

It seems the problem is the engine controller servo switch unit. When I unclipped the arm, the thing started first time and ran like a dream, even after the chilly night we had. Clipped the arm back on, drove around for 20 minutes, stopped at the servo to fill up with Victorian winter-grade diesel. Came out after paying and wouldn't start. Unclipped the arm again and away she went.

So, the question is, how hard are these units to get hold of and where would be the best bet in Geelong ? Having found one, any hints/gotchas for a newbie in replacing them, or is it just a bolt off, bolt on job ?

Thanks
Andrew

Andrew,

If it is the gizmo I think you are talking about then it is the EDIC motor.

It has an arm on it connected to a rod that goes to the injector pump.

They are dead easy to change, unplug the wiring and then unbolt. The installation is reverse of above.

Just make sure it isn't some other electrical gremlin preventing the motor from being driven by the vehicles electrics.

Does the car flat out refuse to start? Or does it fire, run for a couple of seconds and then cutout?

The EDIC motor is tied in with the oil pressure sender. If the engine doesn't reach oil pressure in a certain number of seconds it shuts down the engine.

This is to prevent siezing of the engine if it runs backwards. The Toyota H, 2H and 1HZ engines can be run backwards but the oil pump doesn't work in the reverse direction.

Hi Geoff,
Yep, that's the beastie alright.

With the arm in place, it flat out refuses to start. With the arm removed, it starts and runs fine.

Sounds like it shouldn't be a hassle to replace, provided I can lay my hands on one.

Hi Oldpop.Well, I finally got the chance to do an oil change, new filter and 15w-40 oil. Still the same, the EDIC works occasionally, but not all the time.

Hi Andrew

Good to check things like the oil first. Work on a principle of checking the simplest things first. I have heard of people pulling their EDIC motor apart and finding it is just a seized bearing. Not sure on that as I thought they were a sealed unit. As others say they are easy to change.

When I had my 60 Series had simular problem but it mine happened when I was driving along.The oil senor was faulty and it kept trying to shut the motor down by activeating the EPIC motor to cut off the fuel.I replaced the Sensor and had no more problems.

Wreckers will be your freind but they arnt cheap 2nd hand been there done that

there is a modlue that controls edic motor function but he edic motor can shag out as well

get smeone to glow and start then stop the vehicle while you are watching what the edic motor does. from memory as soon as you put the key to glow the edic motor should pull right back to overfuel start position - wen started it should move forward a bit to run snd when turned off forwards to stop. The low oilcutoff will operate after about 5 seconds but it is common for it to kick in after a cold start but it should run properly after a second start

sorry I will reiterate - there is a control module I cant recall the location that controls edic motor function - they can and do crap out - the motor itself may not be at fault

Had the same problem. Not the EDIC but an earthing problem. The lecko found a short in the rear indicator light. Then the Glow Plug timer stopped working and the plugs were burnt out.
Replaced the plugs and had a manual button put in for the plugs. Count five seconds and start.
Had this setup for 8 years.

Hello there, similar help needed - I have an HJ60 with the 2 H. Went to the garage this morning to find the HJ60 making a clicking sound. Opened the hood (engine was off and no key in the ignition) and found the EDIC connecting rod going back and forth from start to shutoff positions and would not stop. I turned on the ignition, didn't start it though and shut off the ignition. Then a few seconds later it stopped.

I then couldn't start it as it was positioned in the shut off position. I disconnected the rod and was able to start it etc.

Any thoughts on why it would start going back and forth with no key & shut off??

Thanks
