How can I test a fuel pump?

If electric, when you turn the key to the "ON" position you should be able to hear a clicking from the tank. If it clicks and the car wont run, open the line at one end. This is the fuel line that feeds the fuel rail. Now have someone watch the line as you turn your key to on. If no fuel comes out find the fuel filter, disconnect the end that feeds the filter and have someone turn the key just to the "on" position. Be careful -- gas could shoot out of the line! If gas comes out, change your filter then see if it starts. If no gas comes out of the line, I would change the fuel pump out. Please be careful when messing with any fuel accessories.
