Just some advice for any future problems with your burner. Remember a oil burner needs three things to fire: air, ignition and fuel. If it's short one of these it will be a no go.
The place to check for fuel between either a external mounted solenoid or internal mounted solenoid is at the bleed screw. All Suntec pumps and variants will have one. If the pump is turning and the pump is good then fuel will come out of the bleed screw in a steady stream without air bubbles.
If then after you close the bleed screw and no fuel is going to the nozzle, you definitely have a solenoid issue. You need to check first that power is being applied to the solenoid and if so, you will need to investigate further to see if you need to replace the solenoid coil, the solenoid valve itself or the relief valve in the pump.
This may seem ridiculous but I suggest to the guys around here that cannot afford to be down, (hydro excavators, contract cleaners, etc.) that they always keep a spare fuel pump and solenoid, coupling, ignitor, nozzle and fuel filter on hand to prevent costly downtime. A $200 investment in parts will prevent a $300/hr. job going bad.
