It could be numerous things . Pump bad ,pump diaghram has a hole in it , pumps vent line ( usually hooked up to the crankcase breather )could be stopped up , this is not likely, though but it could happen, the fuel filter stopped up , wrong filter as a mechanic I know said that some pumps worked better with certain types of filters depending on wheather or not the motor had a free flow carb as in the tank was above the carb and gravity feed it gas by a gravity flow or if the motor had a pump to pump the fuel to the carb. It could be that there is an air leak somewhere causing the pump to lose its vacuum . Also ,the fuel outlet in the tank could be stopped as in theres something over the fuel tank outlet or the line could be stopped up , the line could have a pin hole in it. The fuel pumps innards could need replacing as they could have deteroiated with age. Also , where did you check to see if there was gas comming to the carb. If you took the bowl off and there was no gas then the carbs in let could be stopped up with something . Take the fuel line that goes from the pump to the carb off at the point where it connects to the carb and see if there is gas there , have some to crank the motor over while you aim the hose away from anything flameable to see if the pump is pumping . If a nice strong stream comes out then the pump is fine and it's in the carb . If not then pull the line off at the pump inlet and see if any gas drains out the in a nice steady stream , if so then it's the pump , if no gas there then take the line off from the filters outlet and see if any gas comes out there , if not then it could be the filter , then take the line off at the filters inlet and check for good gas supply there there if there is at the inlet and not the filters outlet then the filter could be bad , if it is the see through kind check to see if there is any trash in it and see if you can freely blow threw it from both directions or ends. If no gas at the filters inlet then your either your out of gas or there is something blocking the fuel tanks outlet hole or the lines stopped up. While remving the fuel lines examine them to see if you see any cracks in the rubber on the inside or outside of the hoses or any kinks or air leaks . Sometimes the hoses break apart on the inside and the broken pieces of rubber gets into the filter or carb jets and stops them up. If there is an air leak or a bad connection where the fuel lines conect to the filter or pump or the carb. then a screw clamp may fix the problem . If your carb has an electric pump by some chance check to see if its getting voltage and a good ground. If your carb has the electric shut off screwed into the bottom of the bowl check to see if it's getting voltage and is grounded good . Have someone ( or do it yourself ) to turn the key on and of while you listen for a click and then turn the key on and turn the motor over while you listen for a click again . The click is the electric shut off ( also called a solenoid , but don't confuse it with the starters solenoid that lets the starter turn over )engaging . Even if it is still clicking and getting voltage , I usually take them off anyway and turn the key off and on ( with all the safety switches engaged , just like I was going to start it ) to see if and to make sure that the needle is going to pull in and out. Some of the newer fuel solenoids have a ground wire as well as a hot wire ( two wire plug ), but some just have a hot wire ( one wire going to the solenoids plug ) and they ground through the carb. Also check the electrical plug where the mowers electrical harness plugs into the solenoid for a bad connection. So as you can see there could be several reasons as to why it's not getting fuel .
