well I've taken off and cleaned the check valve on the fuel pump and still no joy. any ideas any one?

Can anyone explain to me why loosing pressure via the check valve doesn't effect cold start up aswell? Is there an automatic choke that dumps fuel in when cold?
Cheers

when its hot if the fuel is not under pressure it turns to vapour and you cant inject that very well..

and yes there is an over fuel system for cold starts controlled by the ECU and temp sensors, its done in the fuel mapping on the ecu
