Not enough info here ... what engine is in the car. If it's a v8 it involves removal of the water pump. if that is the case I recommend replacing the distributor as a unit, as there are seals that fail and cause drivability issues, as well as no start problems.

On a 1995 Chevrolet Caprice Classic, the distributor cap and rotor are located on the front of the engine, typically near the intake manifold. The distributor is mounted on the engine block, and you can access the cap by removing any obstructions, such as the air intake duct. The rotor is situated inside the cap and can be accessed by removing the cap itself.
(This is from the 91 Caprice service manual for the HEI ignition system) Looking at the distributor cap from the front of the engine bay, and running clockwise around the cap from about the 1 o'clock position, the wire numbering is: 3,6,5,7,2,1,8,4
To replace the rotor and distributor cap on a 1992 Caprice, first disconnect the battery to ensure safety. Remove the distributor cap by unscrewing any retaining screws or unclipping it from the distributor. Next, take off the rotor by unscrewing it from the distributor shaft. Install the new rotor and cap, ensuring they are securely fastened, then reconnect the battery and start the engine to verify proper installation.
Change spark plugs and wires, change all fluids, check o2 sensors, distributor and rotor cap possibly, change all filters...and a fat wallet...

Not very for a mechanic. If you want to do it yourself get a shop manual. Make sure the negative battery terminal is completely disconnected. It just involves removing the air cleaner, distributor cap, and distributor hold down bolt (pretty sure is a 9/16. Also, are you sure you want to change the distributor? Did it fail, my 89 Caprice Brougham's distributor is fine. If you are getting bad ignition it is probably not the distributor. Check for cracks.
There is no "chip" that can be replaced in the distributor, it is serviced as a unit. There is no chip in the distributor cap.
The cap and rotor are considered wear items and should be replaced. No repair options are practical.
you got water under the distributor cap
