Bucking and serging(distributor)?

I have a 97 Wrangler Sport 4.0.

I want to change the stator (CPS) on the distributor.

Can I do this with the distributor in the engine? What is involved beside taking the screws out?

Thanx

Code 12 is common and really means nothing.

Code 55 is end of message.

Code 21 is oxygen sensor. There are two of them. Get a scanner and read which one needs to be changed.

Went to Autozone today to have them scan.
These are the printed results:
Troubleshnooting PO132> Heated O2 sensor, bank 1 sensor HO25111 high voltage.

O2 sensor defective. Fuel system running rich. Check other codes 1st. High fuel pressure-fuel return line blocked or pressure regulator defective. Fuel pressure regulator leaking.

PO138: Fuel system running lean or rich. check other code 1st. Engine misfire>repair. Fuel pressure very high or low fuel pump or pressure regulator.

So, this is telling me what?

What I know is that The tank was replaced and a used fuel pump assembly was put in 8 months ago. I'm not really wanting to pay for new pump until I get an idea that this, indeed, is the problem. Pump with labor will be around $700, which means I'll probably drop it myself.

Any input would be much appreciated. Don.
