Just installed this 24V 2H into the FJ60 body. It ran perfectly before we pulled it out of the rusty HJ. Now, it wont start.

We fully bled the fuel filter bleed screw and the one at the pump. They have zero air in them. 4 of the 6 injectors get "wet", but arent spraying hard. The other two injectors are totally dry.

The only thing I did was replace the diaphragm as PM.

Any ideas of things to try?
 
Pull the glow plugs (so you have no compression and the engine will spin easily), loosen off the injector lines (a turn or two, not more) at the injectors and crank till all injectors are spurting fuel. When they are spurting fuel tighten them down. Make sure the glow plugs all have continuity and replace those with an open circuit.

Also check that the EDIC is putting the injection pump into "start" mode.

After that try again.
 
Are you getting smoke from the exhaust when you crank it?

I read the 2H manual today and discovered there is a start position on the EDIC. I thought its was just on/off; will report back in a couple hours.

The EDIC typically has three positions, overinject or start, run and off. The EDIC motors can fail and the controller can fail as well. I'm not familiar with the 2H but I do know the 3B.
 
Maybie the EDIC stays in "off mode".

Try to disconect the rod between the injectionpump and EDIC. If you push it back it will give more fuel for starting and if you pull it forward it the engine will stop. In the middle is normal oparation and it should start.
 
We got the truck to start and run out of a bottle by towing behind a truck till it started. Now the problem is when it cooled back down it won't start.

How important are glow plugs to a 2H? Will it start without glowplugs when it's 70 F outside?

Thanks.

You need at least a couple of glow plugs. Did it start again right away after shutting down? The glow plugs are really only necessary on the cold start, not so much on a warm start.

Ohm out the plugs and see if you have continuity. When replacing remember that Toyota uses several different voltages so take the old ones with you when sourcing new ones. They might not be 24v even if the truck is.

You need to decide if it's glow plugs or fuel related. It will NOT start cold without plugs (unless you have really good compression and then it'll be cranky) and it will NOT start if it is air locked. Is the EDIC system working?

Give us a description of EXACTLY what's going on.
 
What is going on is we swapped a 2H from a 24v canadian HJ-60 into a 12v US market FJ-60. The EDIC control, and Glow Plug timer are both 24v. The engine runs and ran well in the HJ-60 before pulling it out.

We are trying to figure out how much of the EDIC controller and glow plug timer we can bypass. If we need the glow plugs even at warm temps we will have to find a way to operate the glow plugs with 12v.

We have figured out the EDIC can be controlled with a cable.

Thanks for all the help we really appreciate it.

You can probably find the EDIC and the glow plug timer from a BJ60 (all Canadian BJ60's are 12v). The glow plugs can also be controlled simply by a momentary push button switch. Run a wire direct to the glow plugs and through a momentary switch (you might need a relay depending on the amp rating of the switch). Plugs glow only when the switch is depressed. This is what I did on my FJ55/3B conversion but I kept the EDIC and it's controller.

In this case you'll want glow plugs that have the same voltage rating at whatever you're making the truck. If it's 12v use 12v plugs, 24v use 24v plugs.

I made my push button only operable when the key is in the "Run" position. That way something cannot be resting on the button, glowing the plugs when the truck is off.

You won't need to glow it more than 10 seconds.



p.s. Let me know how shipping goes to Liberia. I might be going to Sierra Leone (next door to Liberia) with my BJ60.

As I mentioned earlier to zulu, the best way would be to swap in a 12V fuel control relay, 12V oil pressure sensor and a 12V edic motor. all this can be found relatively cheap from australia. When you did the swap, did you swap the ignition system and harness too? this ties all together. You might also want a 12V starter relay.
If you run the edic with a cable, you will lose the low oil pressure shut off. If you run the ignition system of the FJ, then you need to fab a glow plug switch. searh here for wilson switch, this is what you want. your glow plug relay is also 24V, so you need to bypass it or switch to a 12V.

The 2H will not start easily at all without glow plugs, even if the outside temperature is 35 celsius/95 fahrenheit. basically you absolutely need the glow system.

We are currently searching part numbers. We considered putting in a "wilson" switch to power 10.5v glow plugs, however we realized that if he were to replace them in Liberia they would most likely put in the stock 8.5v plugs.

Therefore we are now looking for a part number for a 12v non-superglow glow plug timer. Can anyone help us out?

Thanks

checked toyodiy.com yet?
 
Posted on the other thread also. I MIGHT have the correct relay here. This relay IS 12v. The problem is I can't read the numbers because of paint overspray. Does anyone have a wire color code that we can compare to the relay I have? The relay I have has a 13 pin connector with 10 wires.

this is a (rusty) edic relay from a 12V HJ60.

make your life easy .. run a wilson switch for your plugs .. and done .!

The only problem we have is we would have to run 10.5v glow plugs. The problem is, if one burns out, Ben cannot get 10.5v glow plugs in Liberia. He can get 8.5v glow plugs however, so if we can make it run on 8.5v glow plugs, that would be preferable.

We will run a "wilson" switch if we can't find the correct glow plug timer.

Jan, that looks EXACTLY like what I have. Do you have a wire pin out on that so we can compare. It looks like the part number you have is about as easy to read as the one I have.

The wires on the one I have, starting with the yellow on you can see clearly in your picture are as follows:
Yellow, Green/Black stripe, Red/Black stripe, White/Black stripe/brown dash, Yellow/Black stripe/brown dash, Black/Yellow stripe brown dash the first four are "medium gauge" wire, the last three are light gauge that is it for that row.

Next row is as follows:
blank, black heavy gauge, Blue/black stripe, gap for latch, blank, Black/white stripe, blank the last two wires are light gauge.

Let me know if that is the same as yours. No guarantee that this relay works.

Are you sure the non-Superglow plugs are only 8.5v? My FJ55 with the '81 BJ60 non-Superglow wiring harness and relays runs 10.5v plugs. The '82 BJ60 with the Superglow system runs 6.5v plugs.

Are you SURE he cannot get 10.5v glow plugs in Liberia? I haven't been to Africa yet but in Guatemala we could get most anything if you knew where to look.

I am not sure of anything. I know Ben will have a much harder time finding the right glow plugs in africa because he has little experience working on cars. He doesn't have the contacts to help him find things.

We looked up plugs for a non-super glow HJ-60 and got 8.5v plugs. Are 8.5v plugs for 24volt super glow then?

With all these glow plug options, it's getting difficult to find the right parts. Thanks for ALL the help guys.

I'd think you got it wrong looking it up. Non-Superglow are marginally less than system voltage. Superglow plugs are much less.

If worst comes to worst send it off with an extra set of plugs and your phone number so you can order some for him. In Guatemala we always had an idea who was flying in from the states and could bring stuff down for us.

Hey, if I end up in Sierra Leone there will be a 'Cruiser head one country over!
