I’ll have a look tomorrow. It’s a bit late this evening. |

First try - 950 rpm using the starter which then dropped to idle speed. Second try -900 rpm on the starter. The starter only spins for a couple of seconds.

This page from Land Rover mentions that the glow plugs operate if the engine is idling and cold.

26A doesn't sound right - you could get that through domestic 2.5mm wiring, and have smoked 16mm cable trying to start 2L diesels in the past.

Generally, from what I've seen, Bosch ECU firmwares are programmed to forbid fueling below 250 RPM cranking speed. So... |

I really do hope that you have found the cause of the poor starting.

Have done more checking today. We had to take a slow motion video of the clamp meter to be able to see the readings
