the pump is in the gas tank you have to drop the tank take the fuel lines loose unhook the fill tube and unplug the wiring harness. then when you get all of that done you have an O ring to remove from the top of the tank to get to the fuel pump to change it out

You may have to be under the car to trace the line. It will run from the PS pump down behind the engine to where it connects to the rack and pinion steering gear. The rack and pinion is on a subframe piece below and behind the engine. The 2 PS lines connect on the driver's side of the rack and pinion, if like nearly all GM cars. The pressure line can be disconnected from the pump (suction out the fluid first or it will leak all over), up at top, and then disconnect it at the rack and pinion. If this fitting on the rack is hard to reach, you may need a crows foot wrench to loosen it and remove-I'm not sure about aleros. After disconnecting it top and bottom, check for any brackets that hold the two lines together, and for a bracket that may hold the lines secure on the backside of the engine.

hard start is AM is most commonly caused by a defective fuel pump pressure check valve, the other stall is issue is covered by the following procedure.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Check that the cam shaft is turning as it may have broken a timing belt. Run fault codes to check for cam/crank position sensor problems.
