I replaced the bottom fuel pump but not sure if the top one is bad. and the filter i replaced about 2 months ago. i checked that second yesterday after replacing the pump and it was still clear. i have only had the car for about a year now and have changed the fuel pump relay twice due to corrosion in the relay itself and the second one being faulty, spark plugs, plug wires, and filter the whole time i have had it along with the an oil change every 3,000 miles or so. someone told me it might have something to do with ecu.
