Ok so I have been working on the kids little citation 253 and had it running good, then all of the sudden it quit. Im sure the fuel pump died, its not pulling fuel through the line as strong as it was. But... I was priming the carb manually and trying to get it to run and POW!!! It backfired so hard it blew the pipe off! I put it back together and now it wont run at all. Anyone heard of this? Any info would be helpful. Thanks

it sounds like maybe pre-detonation where the gas is powerful and blow your exhaust off check the pistons, and rings and crankcase if they are ok, then do a compression tester if you have at least 110 psi

my sled it backfires if there is no gas just like for example one time i hit the kill switch then i turn it back on it backfired loud but nothing happen

Had a Mtn Max do that and ended up busting the skirt off the piston. I think you were just really loaded up and pre detonation happened, i would check compression while at it, cheap and easy to rule out that.
