Hi all I am shaving a little treble with my hj75 Ute
I recently purchased a 88 hj75 Ute with a 2h that has been had a turbo fitted
this motor was tired and low on comp (may have something to do with the previous owner smoking multiple sets of 37 simex centipedes)
The old motor would start but would take some cranking and multiple glows to do so
I’ve since swapped out that motor to a low km non turbo motor witch I’ve then fitted the turbo set up back to
I’ve also had glow plug issues with I’ve bypassed them super glow and now manually glow
now I can get it to start with start ya bastard
And once it fires will run and start all day
but not fire first thing in the morning
If I dare continue to crank I’ll then have to tow start and again will run all day without having to glow again
I believe I have bleed all the air out of the system and the fact that I’ve been driving it this way on and off fir the past month
I believe the edic motor is working correctly but I’m no guro
Any help or advice to nut out this issue would be appreciate
Can you take a video?
You have fuel, "pre-heat", good compression, cables...
Advance little bit the injection pump.
I attended a car that running tight, with a slight advance It improved a lot. And 15° on bolt to open fuel.
Disconnect the Edic arm to IP. This will put the pump in the Run position.
Other than that you need to be certain there are no vaccum leaks in your fuel lines. If she's getting fuel you should at least smell, taste, or see diesel in one form or another.
No diesel at the tailpipe means no diesel into the engine.
If she's a manual put her in gear and tow her for a bit.
White and whilst cranking with it not firing also white I’ve since has a Dyno tube done witch improves its performance and consumption
But did not improve the starting
I had alway had in the back of my mind it was and over fueling issue but it would seem that is not the case
I have also got my hands on a few other fuel control relays witch I also may of thought may be the issue also not the case
if I have a vac/air problem in the fuel line/injectors how would one diagnoses and issue there?
Generally , if you pump the primer, it should get enough fuel to start. You can also loosen one injector line at a time. If there is air in there it bubbles out as the engine cranks.
White smoke is combustion that is too cool. The white is from condensation. It could be low compression, a weak injection pump, injectors opening too early or timing is out.
You can also temporarily replace some fuel line with a piece of clear hose and watch for bubbles, this tells you if air is getting in. If you left it overnight and it was empty of fuel in the morning, you would know air is getting in.
It is quite odd i can start it on aero start one or two short squirts and will fire up
with out any aerosol start it will just continue to crank over with white smoke coming out the exhaust without firing up
now here is and example that has happened I stated the Ute at 7am drove to work about a half hour drive then parked it up for the day not starting again until 6 pm with a short glow it fired up and I there it idle until worm and drive the half hour back home again
had tea went out for a night 4x4 mission getting home at 1am the following morning
I then got up at 7am to start the car to got to work and cranked the motor for about 30 seconds to a minute not sign of it going to start again applyed a bit of aerosol starter and she fired up
I’m not sure of what to do next so far things I’ve tried/Replaced
fuel lines
Water separator
Clamps
Primmer
Has been dyno tuned
Tried swapping out fuel control relay to know working relays
bleed the lines to the injectors
Get a boiling hot kettle of water and pour it slowly over the intake manifold, wait 30 seconds and see if she starts any better. If it helps, you've got glow plug problems. The neighbours may look at you strangely, but it helped me with a 2H that didn't want to run its superglow properly.
I would compression test it to eliminate bad compression. Engines stay warm all day and allow you to drive home, but every morning is a dead cold start and low compression rears its head.
There are two kinds of glow plugs/system used on the 2H. Superglow (or something like that) that starts at 11or 12V for a short time then goes down to like 6V or something for the rest, I believe this system uses a lower volt glow plugs. The “old school “ is the early kind. I would guess it uses the 11v or 12v glow plugs. I would say that the glow plugs are burned out again would need to check again. If you go the “Wilson switch” route I would buy a spare glow plug to sacrifice, hook up the spare and time how long a glow it takes to burn it up. Then use a shorter time glowing manually. When I drove my new to my 85 HJ75 home the glow plugs were toast and the first real cold morning it took a long time cranking to get it started and then it smoked really bad for maybe 15 min before clearing up. Was able to install new ones the next day and the following morning it was cold again and it started right up.
