Does the engine run?....if not the book says it could be faulty ECU, DFI or CAS....and also says to check all connections etc. Check near anything you may have touched when doing the pump. Check the fuel pump fuse.

as hako said the reference signal comes from the CAS then goes through the DFI to the ECU.
Your fault is probably the CAS itself , thats the cheapest place to start anyway, but check all the connections around the front of the engine first, and the big plug on the DFI to the right of the coils.
I had code 46, 47 48 all at same time and it was the DFI. Repco is the best place to buy a CAS.
