Yeah, on Friday morning after the initial problems on Thursday evening it did appear to be running fine on petrol and LPG. I would say the first few revs on LPG were a bit jump/stuttery.Gasy wrote:Is it starting and running fine now on petrol and LPG
Have you checked them earth straps , there's one from engine to chassi
Doesn't the fact that it started ok the next day suggest this isn't a battery issue? Green Flag checked the alternator charging and said this was fine at 14 (not sure what unit that was).cmm303 wrote:Not necessarily.Thriller wrote:Took it to garage, the said they can't identify the fault but it doesn't seem like fuel filter.

Typically is now running well so not sure what to do. One garage just suggested a good service and change of fuel filter.
Thoughts?
You've had symptoms that look fuel orientated but also electrical with the flat battery.
So I would start with the flat battery symptoms and check through all battery and alternator connections (live and earths), fuses, battery condition and alternator charging.
If it still isn't behaving with a good battery feed then move on to decide ignition vs fuel. Unless symptoms are obvious probably easier to check ignition first.
When the van is running well I try to run mostly on LPG once the engine is up to temperature.the1andonly wrote:leaving the electrical issues battery/ignition, you run mostly on LPG.
How old is the petrol/ how much in tank?
modern petrols do not like hanging around unused and may be difficult to start.
probably just another question and not part of this solution
Thanks Bob, interesting read.Bob wrote:The age of the vehicle isn't really relevant, it's the length of time the fuel is storred in the tank that counts:

Almost certainy 14 volts, which is fine.Thriller wrote:Doesn't the fact that it started ok the next day suggest this isn't a battery issue?

yes bob totally agree thats why original comment was related to modern petrols (the fuel not vehicle). I suspect carbereters are more suseptable due to the evaporation rates required, this can be severealey restricted for example by water in the petrol. This later problem is more likely in motor bikes and personally known (300 mile in rain to plymouth )Bob wrote:The age of the vehicle isn't really relevant, it's the length of time the fuel is storred in the tank that counts:
