Hi I'm having a crazy issue with a 2007 Ducato 100 multijet van, will start first time in the morning and if it's been left to stand for around 30 mins or so, will start up no problem. But when the van is up to temperature if it's turned off then when attempting to re start then the starter motor seems to sound as if the battery is flat and van fails to start! Even with a jump start it will not turn starter even tried a brand new battery!! But will bump of a push even when warm! Have tried a new starter but it's exactly the same!!
