Solenoid vale not opening?

Trianco/Monoflame Minor/Danfoss pump(new)
Pump changed due to fault, now the solenoid valve remains closed not allowing fuel to flow ! Lock-out does not "lock-out" but ignitor and fan work OK. HELP !!!

Hi Mark
Have the solenoid valve coil checked and prove there is a signal getting to it from the control box. Also check that the pump has been vented and fully primed. Has the operating oil pressure been set correctly on the new pump.
