After the straps are off ,it should drop a few inches about eight or so ,than you should disconnect the two lines beside the fuel filter that run to the fuel pump,than you should disconnect the third one at the fuel pump,than once complete slowly pull the tank to the passenger side of vehicle,it will take a little foce but will come,it really helps if you could get the vehicle up about a foot or more before starting and you should have more than enough room to pull tank and fuel pump out,undo the two plugs than you have to turn the locking plate counter clockwise thats on top of fuel pump to get the pump out and if taking the tank right out disconnect the main line for fuelling

How do you drop the fuel tank on a 2002 Dodge Grand Caravan to replace the fuel filter?

On most these, there are two tank straps which are bolted to the undercarriage which hold the tank in position. It's easier to do with the tank empty or very close to empty. Place something under it to support it such as a jack and remove the bolts holding the tank straps in place, that should let the tank drop out, then you can remove the connections for fuel and electrical.

How do i change a fuel pump on a 2002 saturn sl1

To replace the fuel pump u must remove the gas tank from the car, to do this u need to have the car as high off the ground as poss, a floor jack and safety jack stands are a must, after u have the car in the air and secured on jack stands put the floor jack under the gas tank and apply light pressure to support the tank, position it between the two metal straps that secure it into the car, remove the bolts or nuts that hold the metal straps at one engine and drop the tank down far enough to disconnect the electrical connector and the fuel and vapor lines and the fill and vent lines, then carefully lowe the tank and bring it out, remove the retainer that holds the fuel pump module in the tank, pay attention to the position of the tank fuel pump module for proper installation of the new fuel pump module, reverse above, in all about a 3-4 hour job with a helper.

the pump is in the gas tank siphon the gas out and remove the straps holding the tank(you will also need to remove the three screws holding the filler neck to the truck box under the filler door.)as you drop the tank you will also need to unplug the wiring to the top of the tank and the fuel lines they are usually plastic clips,but if this has been done before and the clips got broken from the first time they could have put clamps in place of the clips.I have found it much faster to remove the truck box itself and that way you don't have to drain the tank and it stays stationary while you RandR the pump with less chance of breaking anything.
Also did you double check the fuel pump relay under the hood in the relay box,I would start there first.
Hope this helps good luck.
