Riello 40 no spraying fuel

mike007

Hi, Could anyone please help me with my non starting Riello 40 burner. When I turn it on the motor starts up as normal, after about 10 seconds the electrodes spark but no fuel comes out from the nozzle, the burner then goes into lockout. To test for a fuel related issue i opened the bleed screw and fuel drips out, while still open I switch on the burner and then fuel pours out the bleed screw so this to me indicates the pump is working properly ? Is there a way of testing the operation of the solenoid valve on the pump, I tested the resistance of both circuits of the coil and get the correct reading of 1.44Kohms and 1.3ohms. Is there something else I should test for the solenoid operation like supply voltage etc ? Any help would be very much appreciated. Thanks
