LPG li pejode not working occasionally

Friends

I have lpgli 2004 model 1.6 307 vehicle 123 thousand

The vehicle does not work occasionally, the problem started to show the bole for 6 months

sometimes the vehicle presses the ignition does not work, it does this every 2 months, then once a month now once a week

when the vehicle was not working, I was running directly from lpd by giving electricity from the lpg regulatore akud with the intermediate cable

I got a few masters, they didn't understand for the problem.

In short, I noticed something about the word ..

By giving electricity to the LPG regulator from the aquarium, the car was running on gas when it started, but yesterday I gave electricity only from the aquarium. Then I took the steering wheel and worked the gasoline.

I understand the problem is there, I guess it does not allow me to live on the LPG system.
