ok,i have found a genuine land rover workshop manual,that gives very much more dedicated information,but it is not cheap.

thanks got the manual but still no joy ,use manual ref to fault find but

all checked as manual says,, but still no luck fail to get injectors to open ...thanks Louis Bloem

well I will keep on scratching maybe my luck will turn lol

gemsdad · Jan 20, 2016

ok,sorry i could not be of more help,hopefully you will get it sorted soon,lets us all know when you do,as it ads to the knowledge base on here.

will do ,,,,,,and then sell it lol just joking love my freelander drove like a dream when she last drove ,,,,,,,,,, thanks Louis Bloem

Have you cranked the engine with the injectors disconnected? This is bad for the ECU as it can damage the injector driver circuit. The injectors are piezo triggered and as said already, run at a high voltage. Unplugging is bad. You won't see 12 volts at the injector or ground as both wires are floating. Ie driven by the ECU.

hi so what do you think that my ECU has died ...on brown and red /white wires test I get 8v (cranking) key on only I get 0.005 v....test brown lead to battery ground and get 12v ...if that makes sense to u,,,,ps my glow plug does not switch on (replaced with new NO luck ) ,,,,4 leads to glow plug relay brown 12v,, black/red 12v,, white/red 12v but the brown to glow plugs 0v <<<,glow plug tested 100%

Nodge68 · Jan 20, 2016

You can't test the injector driver with a simple voltage test. You can only test the circuit with the injectors plugged in. This should be carried out with a break out connection but back probing will work. However you can't test with a DMM. You can only use a scope for this test.

thanks will do a test on the back prosorry forgot to mention ,,,with idiot noid light it shows that I have a pulsebing of the plugs and let you know what I find ........thanks

sorry forgot to mention ,,,with idiot noid light it shows that I have a pulse

If one of the injectors were shorted, could it pull down the injector supply voltage sufficiently to stop them all working?

bloem · Jan 20, 2016

if this is the case how do I go ahead to test or fault find it lol brain is up in smoke to day ,,,,,lol

What made you think it was electrical...you started off thinking it was fuel and you changed the two pumps....Have you checked that the pumps are working correctly and you are getting fuel, I've just had the same problem, although the pumps were working I wasn't getting any fuel as my fuel lines were ruptured at the five finger joint in the engine bay.

bloem · Jan 20, 2016

hi thanks tiny,,the reason I think its electrical is that I replaced tank pump front pump with fuel filter ,hi pressure regulator sensor ,so I am getting diesel to hp rail and to injectors but injectors fail to open, have replaced crank sensor as I was told that this may also be the cause but no joy sorry replaced glow plug relay ,,tested all fuse en relays not fault all light on dashboard on when key on except glow plug ,,,no engine warning or fault light ,,,,

Tiny1000 · Jan 20, 2016

I would have thought (not 100% sure) that if it was electrical you'll get a fault code - I don't know where to point you unless you look again at the camsensor - you only use it while starting - did you have any trouble starting it when it was running?

bloem · Jan 20, 2016

nope it started first time no problems ,,,,,,,,,,, that makes my mind take a flat spin lol

td4van · Jan 20, 2016

Have you read fault codes?

Have you checked output from cam sensor on a scope?

What's your low fuel pressure reading? If it's too low then the ecu won't enable the injectors

What's the high fuel pressure? If it's too low again the ecu inhibits the injectors

Need to do some quality diagnosis on this with the right tools, equipment and method
