Hi there, this is my first technical post so if i miss somthing please be nice :0)

I am currnenly having a look at a 2l 307 hdi non start. I have done the following.

Checked for fuel supply (low pressure side)

Check for switching at injectors, I done this with a noid light and got a faint flash then nothing, if i stopped cranking then started again the same would happen.

Check inductive crank sensor, for both ac voltage generation and the resistance of the sensor = all ok.

Check feeds/earth to hall camshaft sensor, got my 5v, 12v and a good earth (volt dropped these also)
I have also checked for switching with a led light. = all ok.

I then went back to the injectors and checked for a 12v ign feed......(admittedly should have done this already!) I am getting 1.5v supply to the injector!

This is where i need some help, I cannot work out with my wiring diagram where the feed for the injectors come from, I have checked all live feeds to the ecu and all are reading battery voltage.

I may have missed somthing obvious but need a little guidance.

I have a obd package but it will not read live data whilst cranking so i cannot tell you the fuel pressure or whether the ecu knows whether the engine is spinning (rpm signal)

Many thanks in advance, Matt
