1995 Chevy Chevette Hesitation and lunging

Ok, well, I have replaced the o2 sensor, ignition control module and throttle position sensor. Ran some lucas injector cleaner through it. Checked the spark and its strong. Getting fuel to the tb, just cant check the pressure as I dont have a tester and dont trust it enough to drive it somewhere to have it tested. I put good gas in it out of one of our 5 gallon jugs. I'm really stumped. It's been tuned up. New plugs, wires, fuel and air filters. New distributer cap and rotor. Cut catalytic converter off thinking it might be plugged up. Still hesitating and bucking when I accelerate on test drives up the road. Slows waaay down on hills, Hoping that its not the timing. No vacuum leaks, checked that with some carb cleaner with the breather on. EGR seems to be in good shape. Took it off and it moves fine and returns to normal itsself. Dosent have a MAF sensor. I guess next will be MAP sensor, coil and fuel pressure regulator. But im gonna check the timing first before I sink more money into it. Probably wouldnt hurt to change it all anyways. Then if that dont work, fuel pump is next. Any suggestions would really be appreciated, tired of finding rides and walking.

Well, my problem is fixed. It was my fuel pump. I changed it out my self, figured I would save a few dollars. It took a day to do it, but I made sure everything was done right. Got rid of all the old gas, cleaned the tank the best I could. Installed the pump and now she purrs like a kitten. Its a big weight off my shoulders. Thanks fellers, yall really saved the day. I will be sure to be back if I have anymore problems. Again, thanks so much. Semper Fi !
