Thank you.
So between the solenoid and the actual nozzle then?

Yes mate, if nothing, then work backwards towards the tank (jus tbe carefull around the tank area).

Thinking out loud now, someone will need to confirm, is there not a Vacuum sensor required from the Penlium on a typical LPG setup?, if so, has this been done?

[jonny2112]

Yes there's a vac pipe from the vap to the plenum.
Just removed hose from no 1 to create leak as said. Will start her up and try to force gas to see if there's any activity this side of the solenoid.

[jonny2112]

A cough and a splutter with the hose removed.
With all intact, it does seem to want to run, but can't.

Just noticed your modified post. ECU is a worry as I currently don't have the cable, etc.
they could be readily obtainable, but will need confirmation of the system, though LD seems confident.

Probably the way forward then, just read his post, LD thinks Bigas system, I'll keep an eye on my LPG Forum post for another answers , but LD does know his stuff when it comes to LPG. 

Might be worth posting a Pic of the ECU Control Box.

When I remove the feed pipe to the injectors, there is a pressure release. When I remove the pipe from the other side of the injector there is no pressure.
Is this because the solenoid isn't open when I'm testing, or does it suggest they're not opening at all?
Pic of the box on its way (once I remove it)

ok to Clarify, single pipe from Vap to bank of Injector Solenoids, from Solenoids (probably 3 of them each side), then 3 pipes from each Solenoid, to each injector. 

[jonny2112]

Yes mate, exactly. Single pipe to each bank of 3. Then three single pipes (one from each solenoid) towards the nozzles.

So your getting pressure before solenoids but not after to each injector?.

By the way sent you a PM. 

[jonny2112]

Your inbox is full Chris.
And yes, that seems to be the case.

[albitz]

Checked you've got volts to the injector solenoids ?

[jonny2112]

No, not yet. That's what I thinking about too with my question above.

[zirk]

You might see some volts, depending on what make it is, which your not sure yet, depends whether the Solenoids are pos or neg switched, in theory should see some pulses when cranking or ticking over, but I reckon the minuet you pull a plug off one of solenoids it will throw a fault and crap out, worth a try though.

Jonny post a pic up of the ECU amd or any labels anywhere.
