Two ways to check the operation of the fuel pump. First you can pull the incoming fuel line and hold your finger over the inlet while someone cranks the engine. If you feel suction, the pump is working. The other way is to pull the incoming fuel line to the pump as above and substitute the fuel line with a longer line that you sink into a soft drink bottle bottle full of gas. The bottle needs to be above the fuel pump (I think). Crank the engine and see if the pump pulls gas from the soft drink bottle or other clear container. You will immediately know whether or not your pump works.

Test to see if fuel pump or if fuel pump relay is bad?
The best way to see if the fuel pump relay is good or bad is just replacing it with a new one. Be sure and check the fuel pump fuse to make sure it is not blown. Also be sure and replace the fuel filter as it may be clogged. If all this is good and the fuel pump still will not run is more than likely defective. In fact the pump can be running and still not be able to pump fuel.
