another 92 2.5 running out of fuel

ok a couple months ago I got a 92 wrangler off a buddy of mine has some problem and had been abused and I noticed on the ride home it had a bad miss in the midrange rpms so I have to drive it either at idle or wide open and sometimes it would backfire and miss well come to find out its losing fuel pressure so I started with the pump and when I pulled the pump the tank was trashed full of mud and melted and leaking fuel due to the exaust being cut off so I replaced the tank and complete sending unit with pump blew out the feed and return lines and puled the injectors and cleaned due to it not having a fuel filter on it(has new filter now) still runs like **** so I replaced the pressure regulator still runs like crap wel after reading I replaced the distributor,coil,tps,map,temp,and 02 what else could it be ive cleaned all my grounds and cant get the computer to clear the codes for 02 lean or tps so I need some help guys please this thing is driving me nuts to the point im ready to pull the 35s off and crush this thing
