Question about 2000 Chevrolet Malibu
First you should check your trunk. some newer chevy's have an access pannel uner the trunk liner inside the trunk. you remove the liner, remove the bolts and panel, and the pump is right there. it may take some effort to get it wiggled through, but trust me, it will fit. you must remove the fuel lines and wire harness first, then remove the lock ring completely before attempting to pull the pump through the access hole. if that fails then you need to drop you fuel tank to access the pump. there are instructions for removal and installation of the tank below.

fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

fuel sending unit is in the tank. this is normal after about 75k miles and up. pump and sending unit are sold together. fuel sloshes from front to rear making the float on the sender rise and fall.

REMOVAL & INSTALLATION
(see Figures 1 and 2)
CAUTION The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
WARNING The modular fuel sender assembly may spring up from its position. When removing the modular fuel sender from the tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float.
Gently pull on the fuel pump reservoir from retainer to assure a secure fastening. If not secure, replace the entire fuel sender.
