I wouldnt cut a hole cuz the tank is about an inch away from your body . It is possible cuz my buddy did it to his 91 TBI really slow camaro . He made a door and had to cut his metal fuel lines and use hose clamps and rubber fuel lines to put it back together . It wont work on a 4th gen unless you cut a huge hole . Its a total barefoot redneck way to do it . Ive changed 4 in my 3rd gen (autozone pumps) back in the day and 3 in my 4th gen . Its not a easy task but you will spend as much time trying to cut a hole and fish your high pressure lines out of the way and fishing the whole sending unit out of your fabricated hole not to mention its a unibody and doesnt need holes in it or GM woulda put a door in from the factory . Drop your muffler all your suspension and the two 18mm bolts from your rear control arms and drop the rearend . Everything is out of the way then its 2 15mm bolts to loosen your tank straps and pop off your fuel lines which are plastic on a 4th gen and metal on a 3rd , and your there . Pop your retainer ring change the pickup screen (sock) when you change the pump then reverse the process . It usually takes 4 or 5 hours of hardcore wrenching but it gets easy after you change a few .The exhaust was the hardest to get off for me working off jackstands with a basic tool set . Lol cut it all off and replace it with a flowmaster cat back , its way easier and you will love the sound especially with headers . Its your car but im sure that most everyone who knows how to wrench , especially f bodys like myself will agree with me . Ive had both my cars tore apart and my 96 TA is gettting a 500 horse lt1 built for it as we speak . Its sat for 3 years so ill have to change my pump again no doubt . Oh buy a good bran name pump like an original Ac Delco or a good aftermarket one from summitt

If the engine
cranks over normally when you attempt to start you car, but the engine
does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION.
The engine needs adequate fuel pressure, a properly timed spark and
normal compression to start.
1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.
2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.
3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..
