Citroen CX GTI Turbo K-Jetronic issue

[Bilkob]

Following on from my previous thread about putting said car onto modern ECU, in the meantime, it’s decided to not start, tedious as I’ll need to move it around but not the end of the world as it’s all getting replaced.
Anyway, I’ve narrowed it down to the injectors not pulsing, I have good fuel pressure in the rail, but the injectors seem to be low on volts, 10 rather than nearly 13.....
Any thoughts?

K Jet with electric injectors?

K jet is mechanical injection

Been wrong before though

Yes, you’re right. Mine has L jetronic, and I also think I’ve found the issue. The air flow meter wasn’t allowing any air past it for some reason and I THINK this was preventing a signal getting to the injectors. I blue-taced it open and hey presto- squirting fuel injectors! It still runs like garbage but it’s all coming off anyway and at least I can move it/ haul it off it’s arse now😂

That's not how the system works....
I've never seen a stuck AFM but even one with faulty electrics wouldn't stop the injectors firing.
