Discovery 2 cold start problems

matt101 · Feb 12, 2019

Glow plugs have been replaced with new plugs and a new glow plug relay also fitted. I have checked and they are getting power with ignition on so assume these are working ok (the old plugs were knackered)

Measure the voltage on fuse F1 engine bay while cranking when it refuses to start

Ok thanks I will test this tomorrow.
Your help is really appreciated with this. Will update with findings.

Forgot to say check to be good connection at the earth points situated on that rail near the battery and if there is above 10.5V on F1 while cranking expose the ECU without unplugging it, use a needle to reach pin 3 of black plug from behind(brown/orange wire) and measure on that too

Thanks will do.
Iv just gone and had a quick to now to make sure i know where I'm looking tomorrow and I pulled fuse 1 out, I found that the fuse has got black areas on, I checked the others and found similar on most.
I have attached a pic of fuse 8.
What would cause this? None of them are blown but most show signs of black possibly burnt areas?

It's a sign of wear after staying many years in an unfrendly environment like the engine bay
