Thanks for the reply if I am looking in the right place mine has three wires and the glow plug light comes on and after a few seconds goes out . if as a previous reply suggests it is the black box with the three wires that needs replacing where do I buy it and how much does it cost??

Having investigated the engine it does not have an Edc,where is the fuel stop solenoid? Is it on top of the diaphragm that you alter for the fuel mixture

Thanks for the information I will give this a go

Sorry for not putting the year but its a 97 so assume it has an edc
