The bloody wireless fuel guard was at fault! got it removed, and phone up local alarm co' (Car Electronics Ltd in Castle Boulevard,Nottingham) and asked how much for a replacement.. and they said..

Them- "Sorry. we don't sell the unit."

me- "what? how do you mean?"

Them- "we have too many fail, and customers then get stranded at airports etc.. we no longer advise customers to have it fitted as its such a pain in the ****.."

Me- "so I shouldnt bother at all??"

them- "exactly. save your money."

I was STUNNED.

SO there you go peeps.. if you WFG fails your voltage to your pump will be fluctuating wildly and causing all kinds of problems with the fuelling..
I thought my LINK was broken, but no.
