Eml on help?

[Marc92d]

Two codes are coming up on my focus st225 2009,

•P0087 fuel rail/system pressure to low

•P2178 system to rich off idle bank 1

 

Any ideas on how to fix this to stop the eml coming on I have replaced the fuel pressure sensor and seemed to keep it clear for a week max and it keeps coming on and off intermittently? Any help would be much appreciated. 

 

Thanks 

Marc

No access to fuel filter as it's in the petrol tank already went down that road [emoji58]

I've just had a look on 7-zap and couldn't find a replaceable fuel filter, I assume the 2.5 5 pot must just have a strainer similar in principle to the 1.8/2.0 Duratec HE's.
