Starting issue

I do not believe there is a light on the instrument panel for the glow plugs.

There is a light, top right cluster, an orange coil. I have just has a look, the light was on for less than a second, I didn't start the car Ignition off and on again, and no light the second time.

Cheers mate!

WP? is Willy Pete!

Tested the pump.

Murphys law.. its not, not working, so I can only confirm it is getting 12v to it when it is operational (I can hear pump running and then pull plug, test and can see 12v).

I'll keep checking as often as I can and when it does not prime/purge I'll whack the multimeter on.

I did see somewhere the sealing ring holding the pump housing in needs to be replaced if taken off? I'll replace the seal of course..

I am somewhat sure that they heat on shutdown also, as there is a big current draw after switch off.

But my light has never come on, except for the usual start up check. Still there is a big draw when ignition is turned on for a few seconds which seem more than just fuel pump as my battery voltage goes from 12.5-7 down to 11.8 or thereabouts for a few seconds. Hard to tell once engine starts as alternator is putting out 14.5.

You are correct. They do glow afterwards and I am pretty sure it has something to do with taking readings then using this to help start the engine. Hence why I thought this could be possibly the case in question here! Other reasons are for helping a cold start and even reducing emissions from what I understand.

Try to do somehow to measure with the plug connected to the pump cos i've seen cases when there was 12V in the plug disconnected but dropped under the pump's load due to a bad contact on the circuit/earth...eventually insert neddles into those pins from behind and measure on those.

So I left it overnight and tested the plug on first start up.

No voltage from first approx 4 ignition cycles, then we got 12v.

So now I am going to go back and get a new relay and try that as I do not think it is the pump.

Any other ideas?

Ignition switch.

Check the voltage at the switching terminal on the relay as you cycle the ignition switch.

This morning 10C, ignition on glow plug light is on. Start the car glow plug light goes off. I have, in the past, started the car successfully at -5C
