3B won't start.

[petster774]

Hello all
Had the BJ73 for over a year now. Live in Edmonton Canada. No problems starting in even -35 last year, provided it was plugged in. Has battery blankets and coolant heater. Replaced glowplugs a few weeks ago.
Batteries and starter are strong, but the engine just won't catch at all.
Any ideas? It's only about -5 right now too

I'm in Edmonton too, and this is PERFECT winter weather for us this time of year; odd that it isn't starting.

To my knowledge, if the batts and starter are good its either fuel or air problems, so check:

Glowplugs
Air Filter
Fuel Filter

Worst case it could be the injection pump or something fancy shmancy that someone else can talk about, but I would start easy stuff first.

Does it start if it is plugged in?

try cycling the key 2 or 3 times... Could be a stuiper glow computer malfunction... If that doesn't work you could also try disconnecting the EDIC arm for the moment. As various issues can cause it to shut down the engine, like an electrical short, low oil pressure, or faulty pressure sensor, faulty EDIC etc etc...

3B's are kinda picky about fuel, if it has air bubbles in the line she won't run! Purging the pump is always good practice...

I gotta jet, let us know how it goes!

I'm thinking it might be the american diesel? Is there a difference in quality between the stuff in the US? It's started, but hates doing so every time. Hard to fire, but then runs ok.
This has only started happening after two tanks of US diesel

 

[Kroll]

Maybe you purchased inferior quality diesel???

Check your fuel sedimenter. There have been a few stories of diesel purchased in the US with high concentrations of moisture in the fuel (usually from small community fuel stations).

Have you tried bleeding it to see if there is any air in the system?
Half of the hard starting cases on here are air related,the other half are glowplug related.

 

[petster774]

I'll bleed the bastard, see what happens. Thanks a lot dudes

 

[petster774]

And yes Torqueluvr, it starts np when plugged in.

 

[Eric Winkworth]

Nothing to do with american diesel

If she starts when plugged in it's a glow plug issue or a superglow computer issue...

If it starts fine after cycling the key a few times it's the computer...

If cycling the key several times doesn't do the trick throw some glow plugs at it! Or at least remove and test the ones you have!

Another question Gents;
Still tough to start, and it takes quite a few cranks (10seconds) of the starter till it will fire up. When the starter is cranking, it emits a lot of white smoke. When it fires, its black and white, then it all subsides.
Does this necessarily mean that I'm burning coolant or, worse?
thanks again

If its coolant ,you will smell it.The black smoke may mean some cyl are getting proper fuelling and the white smoke is from cyls that have air or non functioning glow plugs.
I know you replaced the glowplugs,but are they working on all 4 cyls?
Did you try bleeding it like you said you would?
It helps if you give us an update.

Not sure if you fixed your problem but I had a similar problem with my 3b a couple months ago, just bought a bj42, brought it home and it wouldn't start the next morning. had to plug it in and crank and crank then it would finally start. Found out the previous owner had the wrong glow plugs in and it took out the fusible link near the battery. So the glow light was still coming but there was an open circuit. replaced the glow plugs with the proper ones and installed a new fusible link. So i would make sure you have the proper glow plugs, and that they are getting power. Good luck

Please note that the 3B-II and the 3B are a little different with respect to starting and running. The 3B-II found in the BJ73 use a rotary pump with a shut of solenoid in the pump and the regular 3B uses the EDIC system and has an inline pump.

It sounds like a glow issue.

Check your fusible link and connections at the batteries first, then check the relays for operation.

Most of this stuff can be tested with a 24V test light like the ones you can get from Napa for about $10.

Generally, if you have to cycle your key more than once, you're going to have problems. It is far better to turn the key on, look for the yellow idiot light, and then once it has gone out, wait for a few seconds more and then crank.

The absolute most simple test to check for glow operation is with a test light hooked to ground and the glow bus bar - look for the light to come on when the key is put in to the "on" position. If no light, check fusible links and battery connections. If a light, then pull the glow plugs and glow test them - each should light with in about 0.5 seconds of each other.

Once one glow plug fails, the others will follow in short order on most systems due to the increase in current. Some systems, however, will shut down once one plug has failed of the circuit resistance value is out of spec. (this is not a system that is typical in Toyota super-glow systems, however.)

Sorry to resurrect an old thread but I am having issues with my BJ70 3B, if the injector pump is out does that mean when I put a new fuel filter in it, the fuel filter stays dry?

When you say "out", do you you mean removed from the engine? If you mean out as in not functioning, please let us know. If the injection pump is out of the engine, then your fuel filter should stay dry. As far as I understand, your fuel system stays pressured on account of the pump, so if there is no pump installed, then there would be no pump to create the vacuum to pull fuel from the tank, through the lines, and through the fuel filter.


Why do you ask?

Easy enough to check preheat voltage. If it turns over then good but try preheating 2-3 times.

Its hard to remove a filter and replace it without losing the fuel. Thats what the hand pump is for.
But its possible to remove the pump from the engine and keep fuel in the filter in most engines.

But if you are talking about the hand primer pump being "out" as in not working or removed, the fuel will most likely have run back to the tank.
