Welp i took out my glow plugs, and they are in working condition. they all heat up, but maybe not like lava red all along only 1cm on the tip.
They are beru plugs. I've ordered new ones just to, yeah.. now that im in there to say it like that.. Not beru, but Febi, but i guess their fine enough for couple years atleast.
Anyhow, i get diesel at injectors, and my glow plugs work by coupling them onto the + on batteri and - on -i suppose its self explanatory that i get air? :confused: Note i have taken off the immobilizer and alarm in the nanocom.
Still have fault code Engine Immobiliser link fault :( It cranks and cranks...
Might i have a bad engine, aka low compression, head gasket etc? I have coolant leak, but i have found a bad o-ring on the heater matrix which explains the amount of loss..

Should i test the compression? or is the fault code actually just hindering my engine starting over? Note i've not checked if i get 12v (or 11v) at glow plugs directly.. but my glow relay is intact, atleast the fuse........
I have a hotfix, but i've disabled it, without help.
I guess its not the FIP being busted due to me having diesel at the injectors?
I am atleast going to change my leak off pipes from injectors to rule out any air by the injectors.

Definitely check the compressions while you've got the heater plugs out.

My suspicion is that if the EMS code matches in EDC and BECM then that code is not getting to the engine. It must be broken wire or duff connector but which one I don't know. Maybe the electrical troubleshooting section in RAVE would help but I am not on my PC.
 
okay, cheers. any clue how much compression i should have in each? i've bought a diesel compression set. up to 300psi
any links to rave? Cheers

Okay, okay. So i should have about 300 psi then i suppose?

Just make sure they're all within about 10% of each other. If one is a little low then dribble a bit of oil down and repeat. If it stays low then try to pressure some air down with the piston at the top and listen to the inlet and exhaust for leaks.
 
i havent recieved the compression tester yet. but i tested dtthe glow plug relay, it works.

Anyhow, i just found out diesel isnt getting into the injector pipes, when cranking i only hear sputtering. Now note it is parked downhill. if that matters.. (i'd suppose theres air in the tank since its parked downhill, but apparently the fip only spews out air??....

and yes it sounds like high pressure air if that matters
 
Evening peeps, I'm late into this thread.
Checked the intank fuel pump?

Checked the fip solenoid?

Checked the resistance on the glow plugs?

If you lose one glow plug it's a git to start.

Checked the relay that makes the intank fuel pump work?

Bridged the terminals of the fuel pump relay to make the intank pump work?
If you've not done already any of these then please try them first before moving onwards ;)

Intake fuel pump works, i assume, spews out 1dl each 10 seconds ish from after the filter.
fip solenoid works,
glow plugs work,
the relay for the fuel pump i am certain works due to it spewing out diesel when i take on ignition.
And yes i've bridged the terminal on the fuel pump relay. It spews out same amount as relay and bridgeing, just that when its bridged it just keeps spewing out eternally as it should i suppose.....

taken off leak pipes,also fitted them snugly after. No diesel when cranking, same with injector pipes.
 
Might it just be air in the system? Aka, i need to open all the injector pipe nuts and just crank and crank for a minute or so?

I remind i still have Immobiliser Link fault code, too low, logged, current, intermittent.

Glow plugs works*
I get diesel into my FIP*
Stop solenoid works*
Intank diesel pump works, flow off 1 dl diesel 10 ish sec*
It does not appeard that there is a diesel leakage by the outershell of the FIP, and no smell of diesel.
BUT i do have oil drippage from rocker cover down to injector 2, and downwards toward my fip.
And somehow have black marks almost looks like oil has dripped out of my diesel filter, but i suppose that is just some old diesel which collected dust for years.

Crack off all the pipes at the injectors,get someone to crank the engine,as fuel squirts from the pipes nip them up.if you have compression it should start.;)​

Cranked for 1 minute, no diesel coming out :( The sound did not alter either, same air sound
Do i need to bridge the pump relay forcing it to feed or something? i dont know where but i think i heard someone saying this car does not power fuel pump whilst cranking, only while glowplug is on, and the cars on? There was no sign of diesel, odd....???

You say you have fuel up to the FIP, so unless the pump is fecked the only thing is the stop solenoid

But if the pump was fecked, it wouldn't spit out pressurised air anyhow? am i not right on that?
the electronic part on the FIP, could that hinder fuel passing?
Remember, i still have the immobiliser link fault code. I've tested my stop solenoid, and that is functional. Might it be that the fault code activates the stop solenoid? I mean, the stop solenoid works so it aint stuck, but if im not wrong this fault code should in theory hinder the stop solenoid?

Im going to test it if the stop solenoid recieves power tommorow whilst ignition is on.

Will the stop solenoid be powered whilst ignition is on? or must i be cranking or engine already running? If i find out the stop solenoid does not recieve power tomorow i am going to rig a cable to give it stable 12v power (and perhaps even fit a switch if it works) if i get mah p38 started....

I wish i could sort out this fault code i have... i feel it would resolve all my problems.

Your probably right mate.its been a bit confusing with having fuel at the injectors then not o_O

I’m sorry, that is my bad. I just tough i had diesel by injectors due to it laying some diesel at the injector top. But apparently it does not feed more diesel than there already is laying in the injector. It just spews out high pressure air. I guess it always will lay some diesel ontop of tje injectors as long as its not wiped away.

So i guess the fault code is what makes the fip not providing diesel.
So, what can the immobiliser link fault be? I saw a post on a different forum stating that the immobiliser is active when this fault code appears.
Yet my immobiliser and alarm are disabled in nanocom.

We are narrowing it down so there is hope and progress i believe :rolleyes:

Thanks for all the feedbacks guys i really appriciate it :)

Won't the immobiliser fault move the control collar in the top of the FIP across until no fuel is allowed out?

He's tried turning off the immobiliser see posts# 15 and 16. I don't know what diagnostics he's using does he have to write the turn off otherwise it will reactivate? looking at the occurrences it's happened quite a few times.

Have you followed @Grrrrrr 's instructions in the Technical Archive to the letter? If so see post#42.;) we feel your pain mate.
