sorry chaps!
basically, i checked the voltage at the pump connector after depressurizing the system, and it didnt have any!
So i pulled off the plug for the pressure switch, and low and behold it was gummed up with that oxidised green shit. Cleaned it all up, and as soon as i switched the ignition on, it started pumping :thumbs:
next thing is to get dash out and see if abs light is disconnected, as i went for a quick drive and it all locked up when i got on the brakes hard. Maybe sensor failure?
RAN: WAY Too many mate
