Replaced radiator now I have no acceleration......

Sounds like it seized when you shut the engine off after driving it while overheated.

Water pump may be bad,

Not plugs. Go to AutoZone, Advance, or Oreilys autoparts for a FREE scan. Bring pen and paper and write down trouble Code that their scanner shows. Clerk should be able to tell you, but you want the Code so your can price repair.
Once you get Codes you can call and price work. A few can be done without much effort. Unfortunately the ABS may be a victim of heavy braking. The ABS can be checked with a better scanner(Not all are equal).
Try tightening the gascap, although each time you added fuel additives you did that, know that one Code may be related to a loose cap.
Think back about your gas purchase. The cheapest is E85. If you put this in your car, it is not made for it. If this is what happened, then it will give a Mechanic a better idea of everything broken.

Check transmission linkage.

You aren't alone with your lights problem . Mu '59 Picanto did exactly the same thing last night. No dashboard, heater, or air vent illumination and worse still no rear lights (note brake lights do work). Got home switched off everything, then switched back on and all working. Very strange.

My first thought would be: If you repaired an emissions hose, take the car back to Auto Zone (or another parts supplier) and let them tell you what code comes up now. You eliminated one problem, now you have to find another.
I wouldn't do a fuel pump without more information.

Sounds like the timing belts needs to be replaced and it is a real pain on those cars best to do the water pump also. I suggest a really good mechanic do the work though. It took me about 8 labor hours to do this.

bleed the system...you got an air pocket in the system.

problem two-try bleeding the radiator to make sure no air locks in it check if radiator fan is connected up and working

there no way to tell exactly without diagnosing. Are you ready to throw yet another guessed part.
