Engine cutting out - Relay 2.2

[ChrisD1981]

Hi everybody,

After the debacle I had with the injectors, which is now sorted. I now have another problem.

The engine idles lovely and pulls really well upto 3K. However, once over 3K the engine cuts out and the engine management light comes on. The code I'm getting is P0093.

I'm going to change the fuel filter tomorrow as I'm not sure when it was done last. I've also had new pressure valves at both ends of the fuel rail.

Before I get into changing the high pressure pump are there any other things to check.

Thanks in advance for any help
