Hi, I know this issue has been raised in the past but I would like to hear from anyone who can help solve this problem. I have an IsuzuTrooper (1999) 3.0litre TD Diesel. When starting up each morning I have to prime the fuel pump by going under the bonnet and prime the fuel pump. Once I have depressed the button on the pump six or seven times it starts straight away. Can anyone enlighten me on this matter.
