FBH fault codes
He everyone, recently purchased my discovery 4 and found the FBH not to be working.
I have used this site for info to date and undertaken a few tests but I still can’t get it to go.
To date I have used the PC software to run the checks with the interface loom.
Initially I was getting a fuel pump code, pulled the pump off, blew lines through and checked component, it’s now working!
Everything appears to be working via the software v 2.16 but I can’t run it directly through the PC as it’s saying ‘NAK access denied’ and I don’t have the option of the ‘on’ control.
When I reset it and plug everything back in and run the engine as normal it starts up and runs but stops showing fault code 22h, resistance wrong. I believe this may well be the glow plug and it needs replaced?
Anyone any advice as I am now stumped and where can I get a new glow plug?
Thanks in advance

I know there is a lot on here folks but I’m stumped!
Been at it again still coming up with the same code.
When I have the engine running I try running the component test on the fuel pump for 10secs when complete the green SHR light comes on and everything seems to start up on the unit, I get a bug puff of smoke and it locks out, the FD red light doesn’t come on at all.
Bumping for any help, please!
