Romano LPG problem - Help!

Can any of you LPG experts offer me some advice? I have a Romano multipoint LPG system installed on a '98 RR 4.0 HE which was working perfectly. However, the control box is mounted on the throttle bracket plate and I had to move it in order to fix the EAS fault diagnosed by wammers. I have not done anything else AFAIK, but simply moved the controller and then bolted it back. But now when I try to select LPG the engine dies and I get a line of red leds flashing in time with a beep-beep-beep.
Is there something you can think of that I might check?

Thanks guys.

The only thing i can think of is the control box was earthed through the bracket and moving it broke the earth

:welcome2: hi , check that the feed pipe isn't kinked or trapped and also check that the terminal feed is connected properly " lts the blue cable with a white plastic connector " i think , just have a good look round where you was working and also as previos chappie said double check the earth , it sounds as though you have disturbed something and not serious . hope this helps cheers mozz

Yes, thanks guys. Darkness fell and I had to leave it for tonight. I'll have another go tomorrow.
