how do you mean mate there is no live feed to the glow plugs when you turn the ignition on...?

[Gsi3.2]

I think he's saying that the Glowplug relay is U/S benny, hence, if he bridges out the battery to the glowplug power rail it will glow the plugs and start really easily..

i'll stratch my head for a while and have a brew.. maybe it's location will come back to me...it is definatly under the bonnet thou..

cheers lads for rply cdti have you had your brew yet???????? ive looked again in haynes man but it doesnt tell you witch realy it is going to be, ill wait for your ideas, because ive run out of them.

bennie its like gsi 3.2 said if i turn on the key its not sending a live to the glow plug rail hence no heat to glow the plugs but if i run a piece of wire from rail to live termnal its ok and warms the glow plugs and starts, ???????????????

I don't know the actual engine setup that well, but the glow plugs should warm up for x amount of time from when you turn the ignition on, they will stay on longer if the engine is colder, so obviously there is some kind of measurement circuit that powers the glow plugs for a time proportional to the temperature of the engine.

Obviously this circuit isn't working, so the fault may actually lie in a sensor that is reporting that the engine is already warm when it isn't - on a warm engine, the glow plugs don't activate at all.

Sorry I can't help any more than this, just that the fault is not necessarily on the actual glow plug circuit but with whatever activates this circuit.

cheers robz for reply ut im still no closer to finding the falt but ill keep looking thanks pal

do they heat up every time you start the car though ? i've been told they dont ! is this correct ?

[Gsi3.2]

They don't have to, no.. it's all down to if the ECU says it needs to..

but if it won't start without glowing, it obviously needs to..
