cheers for your response my pump is near the cylinder and when i turn the programmer on the wall on the pump kicks in but absolute nothing on the boiler if i disconect the the connectors at the pcb everyone turns a red led on except for the one which is at the back which looks like its wired to the ignition probes hope this makes sense cheersIs your pump wired to be supplied from the boiler?
Have you checked for a call for heat at the boiler?
