hi cheers for the response. have tried leaning of the mixture by turning mixture screw anti clock bit by bit the more i do it the more dificult it is to start. also have noticed that i have no lives to the tps, cold start valve, and a couple of others round the back of the inlet, the only one that has a live is idle control valve which i have replaced. is it possible i have missed somthing when refitting the engine or has something gone tits up any advice is great thanks. also checked lives going to the black fuel ecu with the ignition on, only one live in, is this correct or should there be more cheers mike
