hi my mums bought a td5 discovery and been having a few issues but no fault codes have came up on the hawkeye. a couple of time she turns key on everything normal but totally dead no turn over and then today she got in it started it and moved it then turned it off, then after a few minutes went to go out in it, it started for half a second then stopped. (This is the ECM not getting code from BCU I think). Then it just turned over no fire she then locked it, left it 2 hours, unlocked it and it started fine. any help would be great cheers.

Wonky cell in battery ? I have same problem just now. Maybe cold has highlighted dodgy cell.
 
Weirdly, I literally just came across my list of possible suspects and associated fixes for a similar problem I had;

Listed by location and ease of fix (mine was a defender TD5 so maybe some differences);

Drivers seat
  • Oil in ECU (contact cleaner)
  • Relays under drivers seat (faulty or corroded - check crimps - yellow is fuel pump)
  • Bad ECU earth (run new from battery)
  • Check for chaffed loom going over transfer box (from centre seat/cubby)
  • Crank Position Sensor (top of bell housing - check sensor/cable/connector)
  • Purge fuel system again
Engine bay
  • Inertia switch on bulkhead (check connections)
  • Injector plug (fos of engine - contact cleaner)
  • Check wiring where it passes engine for melting/chaffing
  • Starter motor connections
  • Starter motor brushes (kit off eBay)
  • Injector harness
  • Injector copper washers and o-rings
Alarm
  • Disable immobiliser (nanocom)
  • Cable from immobiliser to ECU (grey-green on Red ECU connector)
Other
  • New battery (hankook)
  • New fob/battery (lucas 3TXD and program)
  • Kick it
 
When my MAF was bust it would crank over but not fire-try disconnecting MAF and see if she will start quickly
 
Thanks all, I have got hawkeye to switch the immobilisor off, and checked MAF, it was only 3.5v at full throttle, so put new one on, now nearly 5v so that's better. Started on the button since, however she caught fire today when the ace pump overheated.
