hi people, just wondering if you can give me some advice, driving mk2 orion efi today which has fiesta rst lump. Driving along fine and then all of a sudden starts going rough when accelerating, so stopped to check it out, then i noticed when putting the ignition back on that the fuel pump primes as normal but does not stop, and keeps running for as long as the ignition is on. car still starts but is rough when under accleleration. is the fuel pump goosed or a relay etc???? never had a problem with running at all so far!
