multiple gas-methane-is not part

[Supercharger]

Good evening all, today I received a multiple gas methane, which does not, unfortunately, until tomorrow, the other are without a diagnosis, I describe the anomalies in case there was already happened ...
1) DO NOT START THE ENGINE
2) The INDICATOR OF the ****LLO methane ALWAYS MARKS RESERVE (with full tank)


note: (details)
1) vehicle fitted with cng system original fiat
2) in an attempt to start the engine turns over but will not part
3) there is no current to the spark plugs
makes me think of a fault in the electronic management or some mass oxidized...
What do you think?
thanks in advance

hello the fact that methane does not score and the tanks are full the problem and the high pressure sensor located on the cng reducer.(you're pretty sure the tanks are full of methane?)the fuel pump do you hear it turn? there is fuel pressure?the switch inertial and place?

Sensor engine rpm?next to filter of oil, the cable is ruined.
