I've taken 5 small tests and they read towel rack catalyst converter not complete what should I do?

my fuel pump was bad, replaced it, lasted 2 weeks then did the same thing again. then when trying to styart it was spitting out codes, so then I replaced the the main computor, two diff. sensors, new spark plugs. still wont start!

The hissing stops when I press the brakes and resumes once I let off the brakes. Why is that?

from a cold start car will run fine.After it gets to 210 degrees and I shut it off, go into store for about 20 minutes, I start it up and within 5 min it starts loosing power under load. Put it in neutral and she revs up with no miss. Put back in gear and she sputters unless I floor it and power will be normal for a little bit. no codes come up

a rebuilt tranny was put in my jeep now it wont move

started smelling about an hour after 100 mile trip, coming from back , strongest around both wheel wells. Lowered tank about 1" and noticed fuel lines can't confirm that is where it is coming from. Fill tubes seam fine, but is hard to fill lately, must add slow.rear quick fit ends to sender were rusted, bad. but can't confirm leak there. I live 20 miles from town and is my only car so I must have at least 3 fixes per possibility or I'm stuck. Thank you & GOD BLESS

It is my only car, when I drop the tank I must know all possibilities cause I live 20 miles to town. Thanks
