I wouldnt want to go to the hastle of changing the metering head unless i was sure that was the prob..
I know mate, I really hope it isnt this as its supposed to be getting set up tommorow

I've got a different fuel ecu to try when I get home so maybee that might work, someone did mention to me that starting the car off jump leads can kill the fuel ecu, anyone know why as my car was started with jump leads loads of times after the headwork etc..
