No start, no check engine light, no diagnostic

[EldoradoSAM]

Hello everyone,
So my 90 series (kzj95w) has a strange issue. First, when the key is turned there is no engine light on the dash. Engine turns over but no start. Bridging TE1 & E1 does nothing.
There is fuel coming out of the injector lines.
Battery seems to be draining.
Glow plug main wire still has 9v after the ignition is switched off..
Any ideas on where to start would be greatly appreciated.

Turns out the bulb for the engine light was blown.
There is no fault codes, yet the engine does not start. Jumping it doesn’t seem to matter..Batteries are dead..

Did you fail to get a fault code because the battery was already dead ?

I'm thinking immobilizer, though i wouldn't know where to start at fixing that ?

Does the immobiliser not just cut off fuel supply? Forgive if I have it wrong. The kz is an older gen diesel and if it has fuel, air and compression then it should fire. Only other thought is if the batteries are shot then is it turning over too slow to start?

On the 120, if the immobiliser stops it, the engine actually fires up for a second then cuts. Dont know if thats the same on the 90?
