While running the "brake light,

Replacing a fuel pump has nothing to do with instrument cluster lights or the clock staying on. Unless you shorted wires , did you disconnect the negative battery cable before hand ?
The body control module (BCM) performs the following functions:
• A/C compressor request
• A/C cooling fan
• Exterior and interior lighting control
- Daytime running lights (DRL)
- Automatic lighting control
- Fog lamps
- Interior lighting
• Battery rundown
• Chime
• Gauge control
• Instrument cluster indicator control
• Fuel gauge control
• Temperature gauge control
• Theft deterrent
Interpreting all of the driver warnings sent by the control modules on the class 2 serial data line
Sending the information to the instrument cluster in the form of a SPI serial data bus message
The following list of messages are sent by the BCM to the instrument cluster:
• Fuel gauge position
• Temperature gauge position
• Oil pressure
• Low engine coolant
• Check oil
• Volts
• ABS
• High beam
• Low fuel
• High temperature
• Washer fluid level low
• CRUISE
• BRAKE
• SERVICE VEHICLE SOON
• Door ajar
• Seat belt
• THEFT SYSTEM
• PRNDL
Check the fuel level sensor wires , the fuel level sensor is a input to the BCM .

no year, car, are you kidding??? NO YEAR?
that makes any answers impossible.
speedo dead, but is odometer too?
gas gauge dead,
ABS full time failure
Brake lamps same (in dash or rear tail lamps too?)
does car drive?
does engine run.
is the CEL lamp on driving? check engine light or SES lamp.?
sorry for 20 questions but its a complex machine, and me blind. .

Yes it may be the wires are shorting or its actually the problem with instrument cluster.
Also get the vehicle scanned for any error codes stored in computer this will confirm whether is short circuit issue or actual problem:------

-------------These will help.Thanks.

the brake fluid reservoir is on the drivers side of the engine back by the firewall. I believe the cap is yellow and should say brake fluid or DOT3 or something simular. Use only DOT3 or DOT4 brake fluid from a sealed container.

You can also consult your owners manual to find it.

sounds more like maybe bad temp sensor

the traction control system works off of the abs system so there is a code in the abs module that needs to be pulled so you know were to start to check the system out.the service engine light is a different system all together and there is a code in the ecm that must be pulled so you know were to start to check to repair that system.you don`t say why you jumped to the conclusion that the gas cap set a code.the emergency brake light will come on if the e-brake is not all the way in the off position(something may be holding the lever up just enough to put the light on.the switch could be misadjusted and needs to e readjusted.

you are low on oil in the engine- brake hard and watch the pressure gauge it will drop also---you are at least 3 qt's low.

is the distributer in correctly those only go in way only and there is no adjusting timing on those motors assuming it is the vortec motor

It is your battery. Replace it and you will be good as new.
It has happened to me 2x now.

the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running.
