Hi Pleiades thanks very much for your reply I had already done test 51 without success, the connector under the tank was a bit crappy and the fuses in the fuse box were marked the wrong way round, once I had found the right fuse it was actually blown so due to your help its all working again. Done test 51 works fine. Only thing now is what did the fuse blow in the first place. Hopefully it will keep running and hopefully no damage to engine. Many thanks Alastair
