Where is access to fuel pump without dropping gas tank

SOURCE: fuel pump

you don't have to drop the gas tank. if you pull up the carpet in the trunk, there is a hatch that opens directly above the fuel pump for changing it.

Many of the Pontiacs of that era up to even present models had an access panel in the trunk that you could access through the back seat pass through.

Its been a while since I seen the inside of a Firebird, but in thinking about it the back seat pass through may not be present on the Firebird, but it may be worth the time to lift up the carpeting in the trunk area and see if there is an access panel to the fuel pump.

Check under the back seat for an access panel to the pump. Might be the pump or just the level unit. Good luck.

2003 Grand Am GT,You have to drop the fuel tank,remove heat shield,remove all lines,electrical plug ins,then you are ready to do straps,be sure to go get extra nut and bolts for straps (2) of them had to cut off old ones,once straps are off depending on how much gas is in the tank used jack to lower tank,fuel pump was a twist off with locking mechanisms on top of tank,used a rubber malet and screw driver to loosen,pull out after diconnecting plug ins etc,replace blue plug in for harness to fit new pump,was recommended since it could corrode,lifted tank back up connected wires,lines etc,put key in on position 3-4 times for pump to pump,car started 1st time,my first fuel pump took my son and I 2 1/2 hours,new pump $250.00 wire harness $15.00 and two new nuts and bolts $3.25

SOURCE: Can the fuel pump be accessed and replaced without

Yes, get a torch and burn a very large diameter hole through the trunk area and down into the gas tank. If you are still alive after the explosion, the pump will be right there and you can change it.
