Recheck the connections some connection loose, bad contacts, use the VOM for some wires open or break. with alternator/ignition see the diagram attached. If the problem persist RUN the scanner/computer for easy diagnostic and fix it.

SOURCE: Toyota Landcruiser ute HJ75 2H Dsl 4lt starting problems

Sounds like pump timing is out of sync with engine crank and camshaft. Utterly crucial on a diesel engine. all needs to be pinned in place when refitting chain or belt, then pump timing sho uld be set up with a dial test indicator. A job for someone who knows what their doing. Before considering buying this carry out compression check as if timing is out between cam/crank tow starting could have bent valves!

Hope this helps!

SOURCE: 1997 VW JETTA DIESEL GLOW PLUGS

You have to replace the defective glow plug. You can test the glow plug without the test light. Just put a wire on the bolted end of the glow plug and connect this to the battery (+) terminal. Then, put a wire around the body of the glow plug and connect this to the battery (-) negative terminal. Hold at this position for a minute or less. Good glow plug will heat up.

As far as the wiring schematics, I will just describe
it. Your ignition switch is connected to the positive
terminal of the battery by way of the fuse in the fuse
box. From the switch it goes to a timing relay before
going to the glow plug terminals. The glow plug body
is screw mounted to the engine block which serves
as the negative terminal. So, as you switch your
ignition, it heats up the glow plug enough to give a
combustion of the atomized fuel in the cylinder piston
of your car causing it to run.

which one.?
then learn the injector and glow plug controls. (books)

the "basics of Diesel)

1 bad glow plugs? (lots of ways)(or power or controls)
2 weak compression (a cold engine need max here)
3 or bad fuel injection. (or no air supply, clogge air filter, or?)

to solve problems you can do simple tests.
it's all in the manuals.

Glow plugs not working after changed alternator to internal regulator?


see the diagram attached for charging/ignition. and recheck any connection wires for loose, corrode, or open or break wires with VOM. If the problem persist you must RUN the scanner/computer for easy diagnostic and fix it.

THIS COMES ALL FROM "WAIT TO START" DO YOU WAIT TO START? IF NOT,THEN THE GLOW PLUGS ARE BUR'NT OUT,WHICH YOU WILL NOT NEED UNTIL FALL. OR MAYBE YOU'VE GOT IT HOOKED ON EITHER,STARTING FLUID,IN WHICH CASE,I SUGGEST YOU REPLACE THOSE GLOW PLUGS NOW.OR ELSE YOU'RE MOVING ON TO EVEN WORSE ISSUES.LET ME ASK YOU THIS,WHY ARE'NT THE GLOW PLUGS BEING DENIED POWER? AFTER ALL THEY START THE ENGINE? AFTER YOU INSERT THE KEY INTO THE SWITCH,WAIT TO START,LIGHTS UP.IF YOU'VE NOT WAITED UNTIL THAT WAIT TO START LIGHT GOES OFF,,,YOU'VE BURNT THE GLOW PLUGS UP.THE ONLY THING TO DO IS REPLACE THEM ALL.IF YOU'VE BEEN USING STARTING FLUID OR EITHER TO START YOUR ENGINE FOR A LONG PERIOD OF TIME,FORGET REPLACING THE GLOW PLUGS,BECAUSE YOUR ENGINE IS ADDICTED TO THE BOTTLE(EITHER) YOU MAY BE ONE OF THE LUCKY ONES,REPLACING THE GLOW PLUGS MAY RESOLVE YOUR ISSUES.BUT,WAIT TO START,,AIN'T NO JOKE. BEST OF LUCK TO YOU & YOURS!

Hj75 was driven to where parked now wont start


hj75-- make sure you have fuel, then on the right hand side of the motor is the injector pump "(do you know how to bleed it?)
if not you may have to come back and i will walk you through it but first , get some aerostart ,or starter fluid,take the top off the air cleaner and after the heater light goes out squirt the starter fluid in the top of air cleaner,NOT TOO MUCH .that will make it fire ,best if there is two of you ,so that turning the motor over and the fluid spraying happen at the same time.if it misses a lot when it starts you need to get your glow plugs checked .if it doesnot start after 2 goes like that then you will have to bleed it.if you want help there come back and i will walk you through---- let me know what ever happens "youdoit"

I have an 1983 HJ60 Diesel Landcruiser with 4.2 N/A Diesel Engine. During the day it runs fine and starts fine. First thing in the morning it just keeps turning over without starting until the battery is...


have you fixed this problem? if not ,here we go ,hj6ocruiser had 4lt a,2h engine if you have a 4.2 ltr engine in yours it will be ,a 1hz motor and a bugger of a job to fit(i have only done one and even though i have been asked i wont do another) the point being ,with out modification the 2 glow systems are not compat able the early 2h had 11 volt glow plugs then they went to 6 volt with a largeglowplug in the manifold (manifold heater) the 2h did chnge to the superglow system but not untill 1995 (in australia anyway) if you did not change the timer you will find you burn out glow plug s pretti regularly. if you brought it to me ,iwould remove,check and re place (where necessary)all the glow plugs and the manifold heater .then run an independant 12 volt wire, after disconecting the existing feed to the manifold probe, the new wire runs through an
independant switch fitted on the dash board to the manifoldheater.there
is no doubt in my mind that this is the soplution to your problem----- the quick fix is asquirt of aerostart into the air cleaner as you co to turn her over or else loosen the wingnut on top of the air cleaner a teaspoon or so of petrol at wingnut and fire her up, aerostartis best ,if you can let me know how you get on i`d appreciate it youdoit
