Ford Mondeo - P1211 P0251, Hard To Start In Morning, Glow Plug L - ss786

My mk3 mondeo tdci 2.0 has developed an issue for last couple of weeks. Glow plug light starts flashing and there is a loss of power when car is accelerated sharply or under heavy load.

Also, it takes number of attempts to start the car in the morning. Pattern seems to be that longer the car has been parked for it would take longer to start the car in the morning. Once it has started in the morning it starts easily for any consecutive attempts during the day.

Both the above symptoms started happening at the same time so I guess they are caused by same issue.

I bought Ford Super F Scanner and hooked to Mondeo, which shows p1211 p0251 after glow plug light flashing.

I have done following things so far in the hope to fix the issue but no luck:

  • Changed Fuel Filter
  • Cleaned EGR volve
  • Added REDEX diesel additive into fuel tank
  • No visible fuel leakage near fuel injectors or frond of the engine
Can anyone please point me to right direction to where the problem might lie?

Thanks

I think this is a fuel pressure related problem. Try a piece of clear plastic pipe in the fuel line after the filter & check for any air bubles. If no air, replace the 4 injector leak-off pipes with clear plastic tubes & check for excessive leakage from one or more injectors.
