Hello. I have Opel Frontera-A from 1995 year and engine C20NE.
Petrol and LPG.
Always started on Petrol then go for LPG. One day tried to start and no response.
Engine try to start then stops, sometime start and work like on 2 cylinders and no response for accelerator then stops.
I checked DTC's by flashes and only 31 and it is normal when engine no running that it no reads RPM sensor. No other DTC.
Checked fuel pressure and when starter work it is 2,5 Bar.
Checked ignition and spark exists.
Checked timing and it is correct.
After few tries when i unmount spark plugs 3 of 4 are wet and one absolutely dry.
I do not know what could happen i was driving normally and shut down engine and next day car was dead.
