No response when turning key to second position

Hello chaps, I am in need of some advice on things to try to resolve this or recommendations for a garage/auto electrician in the north west I can visit.

If I turn the key to the first position I get the glow plug light. Wait for that to go out and turn to second position then I get absolutely no response.

This issue has been going on for some time, even before the rebuild but it would be a rare occurrence. Normally it would resolve if I waited a while and had another go. I had an incident about 2 months ago where I stopped for fuel and then it just refused to start up again. 20 minutes I was trying and eventually got started which to that point was the longest it had taken to resolve. Then it was all fine up until this week. It's been 4 days and it shows no sign of wanting to get going again. I'm not sure if the issue has just finally got to a fatal point or if it's being made worse by the hot weather.

I made this video that shows the problem:

To be honest I don't really know where to start. The effect is the same as if I try to start without disarming the immobiliser (minus the immob light coming on) so I suspect maybe it's something to do with that.

If anyone has pointers on what I can try to diagnose this I would appreciate it.

Two things instantly spring to mind.

Either a dead starter motor or a faulty ignition switch. Have you ruled these out?

I've just had a similar problem but i don't have an imobiliser. I traced mine to the starter relay behind the fuse box. There are 4 wires, 12v positive in and then out to the starter, ignition fed 12v positive and an earth. I confirmed a good 12v supply to the relay, a good ignition fed supply and continuity from the relay to the starter. The problem turned out to be a dodgy earth, sometimes it was ok, sometimes it wasn't. I wired in a new earth, it cured it straight away and i'ts been ok since.

Not sure if it will help but there is a similar discussion on the TD5 area and it suggests a problem might be with the relay or instrument cluster. Jeff

With immobiliser disarmed is starter relay clicking Question when you try and start the engine Question

your starter relay coil is control one side from ignition switch. and other side alarm too ground (battery neg ) and switched output from the starter relay is controlled by immobiliser too

As your glow plug control seems to be working and is controlled by ignition switch. at same time as the starter relay and from same ignition switch output that ignition switch is working ok

With alarm and immobiliser disarmed from your key fob work way down starter cct with voltage tester and find witch part of the cct and control units as failed

Thanks for the advice guys. I'm still not that mechanically inclined and trying to learn as I go so appreciate all the pointers.
I had a little bit of time today so popped out and confirmed the ignition switch is working. I should get time to work through the rest of the advice at the weekend and hopefully report back with success.

As what whirly90 said , but we had the remnants of an immobiliser but a spider plug had been fitted to the plug in the seat base. Traced it down to the starter relay base there was no connection to earth. Checked continuity of all other wires and the operation of the ignition switch and starter motor. Replaced earth to a local boss and alright now. The issues started off intermittent but gradually got worse so suspect now that the earth wire had broken somewhere and was only sometimes making contact to crank the engine over.
Hope you find the issue.

I spent yesterday tracing wires and checking continuity. Everything up to and including the starter relay seemed good so continued on and got to here:

I was following this black cable at the back and it seemed quite awkwardly positioned the way it comes around on itself. I pushed it to see if it was secure and it barely moved. Decided to try starting it on the off chance and it fired up straight away. The connector had just worked its way ever so slightly loose.

Feeling a little embarrassed now that it turned out to be something so simple. At least it was a good chance to learn.

Thanks everyone for your help. Now I'm off out for a celebratory drive.

Well done. Excellent result.
Nothing to be embarrassed about. Just part of a ( steep ) learning curve with Defenders.
