OK interesting. I'll try that this evening. Disconnecting hot start will be more difficult than you'd think due to way it's wired in!

Usually hot fix just picks up a switched live and ground and is connected to each end of the cut sensor signal wire. Just disconnect signal wire from hotfix and join back up. Should be a grey wire with a blue tracer.
I am sure you can manage it.
That is what i am trying to establish. But reading back i would not think the lamp has failed.

Just disconnect the hot fix, see what you get, one step at a time.

One red herring I forgot to mention was that when I discovered the hot fix box I also discovered that the earth wire had come away from the scotch lock. This was most likely during my manhandling of the ECU as it looked like a fresh break. I have reconnected that wire now and still the light doesn't come on. I'll remove hot fix later and see what happens.
When the temp signal from the ECU temp sensor is below a certain value the ECU activates the glow relay for a varying time subject to temp sensor reading and switches on the glow lamp. It is the ECU that switches the glow lamp on NOT the glow relay. I am thinking the hot fix is faulty. If all is same when it is disconnected then you maybe looking towards the temp sensor first of all. Slowly slowly catchy monkey.

I'm sorry to hear that. My intention was to help you to get the car running. My advise was based on my experience. I did that with my car and ran it for more than 3 weeks in heavy traffic.It was not based on what I heard or read somewhere kind of thing. Infact, my car had a similar problem , it was frequently cutting out on the road. I learned a lot from that issue , thanks to members here specially to N2O.
I'm no motorsport guy or a techie . My knowledge on cars , if any, started from Haynes Manuals.
The injection pump used in our cars is very similar to VP37 found on VW, AUDI, BMWs etc. There are many forums on these cars with a lot of info.
Good luck!

Since when was the glow plug light on a P38 an LED?
Yeah, wondered about that as I'm sure mine was one of those little bulbs when I replaced them all a few years ago. I think it was just slang for the dash light though.

You do seem to be missing the point. The advice you are free with is foolhardy and possibly dangerous. Haynes Manuals were published to help DIY owners, I am willing to bet that no manual would give the inept advice that you have given. That would leave them open to litigation. Thank God that the OP saw the stupidity of your advice. Mainly for the fact that he lives on our island not yours so we don't have to worry about an out of control vehicle on out roads.

Wasn't sure if it was an led or a bulb
Think LEDs are a bit new for the P38! MartyUK has converted his mind and I must say it looks very good.
That really does explain quite a lot.
