You've determined that the old fuel pump is/was working and I would assume that the new one is working also. <img src="/forums/images/graemlins/kewl.gif" alt="" />

If you haven't changed your fuel filter in a while,(I change mine once a year/every 10,000 miles) then yes, it could become clogged and restrict the flow of fuel to the engine.

To check that the fuel pump is working (have someone help you)...

1. With the vehicle turned off, remove the gas cap to relieve the pressure in the tank.

2. Remove the hose coming from the tank into the fuel filter (located on passenger side frame about midway). Be ready to possibly get some gas on ya.

3. With a container to catch the gas, have someone turn the vehicle to the "on" position for a second or two while you determine whether the fuel pump is working. [color:"red"]TAKE APPROPRIATE SAFETY PRECAUTIONS.[/color]

After you've determined if the fuel pump is working or not, you might as well change out the filter if it's "been a while".
