Hi Phil,

There's no such thing as a lunatic idea when

a) your knowledge is as limited as mine and
b) you've already tried loads of stuff and it hasn't worked.

I like your idea. Its got to be worth a try. It definitely seems as though there is a reference being lost when the battery is disconected and something needs to be done to restore it. I'll give it a go when I'm brave enough to disconnect again.

Thanks

Nigel

And yes Phil.I now know that the earth for the fuel pump should only be available once the cam position or crank position sensor picks up the rotation of the engine. Learning all the time!!
