Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC

The fuel pump is in the fuel tank. You may be able to access the fuel tank by removing your bottom rear seat cushion. If no access there you must remove the fuel tank. If you have to remove the tank and it is mostly full you should siphon out as much fuel as you can into appropriate containers.
