Hi I have a transit 2.0 tddi. Takes ages to start, once running you can turn it off and it will start straight away, leave it 3 or 4 mins takes longer to start. Longer you leave it the longer to start. Have replaced fuel filter and head checked and done seals on pipes because it seems like fuel running back. I also did glow plugs. It had a pump 2 year ago. Ps no fault codes?
