SOURCE: ust changed the fuel pump on John Deere 6300 and will not start
Can you hear the pump run when you turn the switch on? If so, you have installed the pump correctly.
There could be an air lock...... there should be a handle somewhere for a manual pump you can loosen a fuel line connection and pump until the bubbles stop and all fuel comes out.

Leo, try removing the fuel bowl first and checking to see if the needle valve and float are working correctly.
Typically, whenever the fuel system has been "shellaced", the small port that lets fuel flow from the bowl into the carb, gets clogged. You can check this by removing the center nut on the bowl to drop it down. (turn off the fuel valve 1st) and be careful not to let the needle valve and spring retainer fall off the float.
Once you've done that, you can spray some Carb & Injector cleaner thru this port and use a small pipe cleaner to make sure the hole isn't clogged. Also, check the float to see if it's got any gas in it. If it does, you'll need to replace the float, as it shouldn't have anything but air in it, hence the term "float".
You should be able to get the carb working fine after doing the above, since you can get the engine running by spraying cleaner (starting fluid?) into the carb.
Here's a link to the B&S site where you can get info on your particular engine by using the model number stamped on the engine itself.
