CPS.... (Crank Postion Sensor) Take it out, Check the wires havent been rubbing against the warm manifold... Clean it up and they can be a **** to get it... Make sure when puttin it back in you get it in rite, Usually best to tap it in with a hammer, But dont whack it, Just tap it, At the end of the day its only plastic...
well solved it now!
it was a buggered ECU and fuel pump. Tried daves ECU on it (cheers dathers) and it seemed better, was getting power to the coil, fuel pump relay, and pump and the ecu light was working, but wasnt getting any fuel. removed the fuel pump and put in a spare one from my old nova and it still didnt work, but that turned out to be because the FI had gone. So now i just need to get another ecu.
If anyones interested i tried daves ecu which is a totally different part number to mine and it seemed ok, and now im borrowing another ecu (cheers chris) which again is a totally different number and its working great. so i dont think ecus have to be the same, the one im using now is even from an xe with no lambda sensor, which mine has and im not getting a fault code.
