    So getting an error code saying pump open circuit to earth. This is on an early daytona. If i feed the fuel pump directly from the ecu rather than via the relay its all good. So assuming a faulty relay. Any way of checking the relay?

    Iirc it is the same spec' 4pin relay as the cooling fan relay mate. Why not try swapping them over & see if that confirms your suspicions.?

    So swapped some relays around and no difference.
    If, at the relay connector, I bridge from the live to the output the pump runs.
    If If take the relay loom out of the eqation and plug the brown plug from the ecu directly into the fuel pump it primes.
    But using the relay loom nothing!
