What sort of LPG conversion is it? Makes, models of items, mixer ring or gas injectors?
Do you know where the injector cut wires have been fitted?

If it now gives a continuous squirt of fuel from the injectors, suspect the emulator and/or the wiring to it. If it's the Landi Renzo i think it is, it's a close relative of the AEB Leonardo, in which case injector cut is on the +ve feed to the injectors (green wire on the injector plugs) but check the emulator first.

I believe that disconnecting the emulator does not arrive + 12V and ground, is it correct? |

It sounds as if you may have to go through the LPG wiring with a diagram and find out if there is a wiring fault on it.

Couldn't find much on the Landi 25 emulator other than it has it's own EV1 sockets to plug onto the petrol injectors. Does it also have plugs to plug into the original EV1 sockets on the car that would have normally powered the injectors?
If so, unplug the original injector sockets from the Landi loom, the Landi sockets from the petrol injectors and fit the original EV1 injector sockets onto the petrol injectors and repeat the test to see if they spray continuously with ignition in position 2. It's "full-group" or "batch-fire" injection so it doesn't matter if you mix #1 socket with #3 socket, all injectors fire at the same time.

No more injectors sprayed. You were right, LR25 or LR25 harness has some problems. Thank you very much for helping to everyone |
