Hi I posted on wrong forum so trying again, I have a P38 2.5 turbo diesel, she has become a nightmare and totally stuck, she fires after a lot of effort, got no revs and sounds as if she is faltering, she has had new fuel pump, new battery, new glow plugs, new fuse box she is getting fuel but refuses to run on anything other than tick over, any advise would be great, garage plug and play showed no faults
