There are a number of faults I'm aware of with the focus which can cause driveability,cutting out and non start problems.
1 poor earth connections in engine bay, you need to check and clean ALL earth connections in engine bay
2 engine wiring shorts out against EGR valve (but this normally blows fuse F9 (20amp) wiring needs to be repaired and re-routed and secured
3 erratic running and non start (glow plug warning lamp flashes when this fault is present) this is caused by low fuel rail pressure and is expensive to put right you need to check for the following fault codes P0109, P0191, P0251, P1211, P2288, P2291
if one or more of these fault codes are present remove fuel filter and drain contents, inspect for deposits(black with silver particles) if deposits are 11mm you need to remove fuel tank and flush it out.
the following will need to be renewed:
fuel rail, high pressure fuel lines, fuel supply line filter to high pressure pump, fuel return line from high pressure pump to filter, kit protection blanking plugs, kit, leak off pipes, fuel injector clamp bolts, fuel filter, high pressure pump gasket,high pressure pump seal,high pressure fuel pump and timing belt.
I recomed you carry out you diagnosis in this order
