There is no main fuse in the camaros and by losing everything its telling me that you have probably blown a couple of the fusible links....they are in line in the wires themselves and look like a piece of black licorice nibs (hope you know what i mean) about an inch long and tubular if you cut out the link and strip the wires and strip them them re-connect them together you should restore the power.......these links are usually near the starter by the soilonoid in the group of wires connected to the big terminal....however i'm not sure how the backfire is related but that should restore the power to everything
hope this helps.........if not let me know ill keep your problem in mind til i hear from you again.....Good luck!

It is firing and has fuel at the fuel rail, but will not start,also it will run on carb cleaner

You need to check the fuel pressure with a pressure gauge it should read more tha 2 bar if it doesn't you might have a blocked fuel filter or a weak fuel pump if they are ok check timing

It could be a relay that keeps the fuel pump running when the ignition switch is in the run position. My jeep had this problem, where the pump gets power in the start position but once the key returns to run, the engine shortly stops running because the pressure in the fuel line drops off as it is used by the running engine, it usually died within 3 seconds. my relay was under hood and there were several of the same type in there, I switched the fuel system one with the one for my AC(which only blows hot anyway) Hope this helps...

1989 camaro 305 run rough and won't idle. Spits

spray some brake cleaner in the throttle body to keep it running and keep spraying and see if you can rev it up. If this produces better results then check fuel pressure. Most likely time for a pump. If this happen all of a sudden I would not suspect the fuel filter as being the cause and I would also replace it with the new pump.

92 camaro with new fuel pump won't start

This does sounds like a carb issue. Like it is out of adjustment from the fuel pump finally allowing gas to flow properly to the carb. Now that it is flooded it will be harder to start due to everytime you are trying to start it it automatically floods out. If you are concenered with your mechanic take it to another shop and have them look at it.

No spark?

well more questions then answers but a step closer.. good fuel pressure? check the throttle body when someone turns it over. did you try starter fluid ( put on the air cleaner for it, so it dont back fire) anyway if it runs on starting fluid then its fuel delivery system. . Basics three things to run. air, fuel, spark. you have all of these? in good supply? then look to compression and condition of dist. cap and rotor.

sounds like the fusable link which feeds power to the ignition switch has gone to the happy hunting ground. this fusable link is bolted to the starter motor battery terminal along with up to four others.
