SOURCE: replace fuel pump in 94 camaro without dropping the rearend?
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

I had a similar problem, took it to get diagnosed and was instructed to give them $1100 because of a faulty reading on the distributer, rather than paying $650 for a unit I found plenty available new for under $200 I bought an OEM for $189. Now the labour can be found cheaper elsewhere. I then discovered that the module may also be at fault but I would have to replace the dizzy first, Then discovered that the Air Flow meter {afm} may need to be taken off and cleaned with a carby cleaning spray, this is a do it yourself fix costing you about $8 a can of cleaner
Unscrew the units clamps and disconnect the plug, I can't stress enough, DO NOT touch the fine wires inside, spray the carbon buildup off the inside and blow/air dry, {do not rinse with water.} reinstall the unit in the reverse of which it was removed, Alternativly you may have fuel blockage in the lines, try replacing the fuel filter {cheapest fix}
Hope this helps

SOURCE: horn not working on 1999 z28 camaro / what could
Remove the horn it's self and try grounding the mount and then put power to the post,if it won't blow try tapping on it.If that does'nt work the try adjusting the screw thats in the rear of the horn to see if you can make it work,if not get a new horn.If the horn blew when you bench tested it then you need to see if you have power to it with a multi meter or a test light,if yes,clean the grounds where it mount both on the car and on the horn mount.If no,then you need to check fo power from the horn button to the relay by useing the test light or multi-meter again and check the relay feed,[#85 or 86 in the relay socket] for power from the horn button.If you have power on either then replace the relay,if not then the horn button is not working and the stearing wheel needs to come off to find out what you need.This replier is assumeing that you have already checked the horn fuse,right?
SOURCE: my 1994 z28 camaro is hard to start when you first
your spark plugs and wires is bad or intake manifold leak and a stop up fuel filter will cause hard cold start ups in morning.
