MBD,

Thanx 4 that , but I am now confused

I have a wiring diagram that shows the overun cutoff and fuel pump relay as separate parts , so do I take it that both these devices are in a single unit ?

Also , maybe you can comment on this , this car has a problem with intermittent cutting out which seems to be worse in damp/wet weather and is accompanied by an increase in fuel consumption , in your experience could the overun cutoff switch be responsible ?
I have checked the other obvious stuff , like ignition wires etc.

Thanx
