I've been having the the classic low fuel pressure problems in my 2.8 crd. Hard to start,constantly having to hand prime to start and press the accelerator. I checked the filter housing for leaks,and the fuel filter everything seems ok.I did the leak back test on the relief valve on the rail and that seemed fine so I was really starting to think fuel solenoid on the pump or dribbling injectors. Anyway today I changed the battery from a 560A 70AH to a 800A 85AH I had to chop the tray but eventually got the bigger unit in place. Low and behold the car started without any assistance !! After a couple of minutes the cooling fan kicked in and then stopped ( is this normal ?) It seems like a different car. Its early days and we'll see how it goes but it's looking promising for now. I think i'll be looking at doing the Leedsman's battery mod as well.
