Hi all

I have a 2006 tdci and have been suffering from a red light appearing associated with a loss of power. I had a friend read the code and it came back as low fuel pressure on the rail. After a further full diagnostic at a ford garage it is now reporting only glow plugs that need changing. Does this seem reasonable ? I wouldn't have thought that glow plugs would cause a loss of power when running?

Any ideas?

Thanks
