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

Check the vacum line to your fuel pressure regulator, the line may have a crack in it or the regulator may be bad. 

Go to the dealer and show them the piece. They will pull up the diagram and match it up. Then you can shop around for the best price

Same problem as I had, that is the beginning, then the car will begin randomly failing to start and then, after a while it will be stuck. You should bypass the entire system. There is a great write-up here: http://newrockies.ca . This was the only thing that saved my Park Avenue.

drsinister69 Is an idiot if u dont know nothing about camaros dont post. The opti spark is behind the water pump but they are sealed that way they do not get moisture in it at all. but if the plug in is not all the way in it could get water inside. to change this out all u have to do. Is take off the fans, take off the balancer pulley, take off water pump, then use a 10mm socket and take off the distributor but make sure it is up on number 1 to get it in time or it wont start
