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
