Loses power while driving


I suspect that your fuel system is faulty. Check for a clogged fuel filter, or if your fuel pump don't run at all, replace the "fuel pump relay". Sometimes your fuel pump will run, but be too weak to hold pressure, which will let your car idle somewhat, but be too weak to run the engine at speed or under load.

1999 chevy monte carlo must have good battery for fuel pump to work


most likely the pump is ready to fail. You will need to get it diagnosed. Its possible the battery is weak also.
Alot of cars will not start with a weak battey but its the ignition system that doesnt fire.

Car runs but when you accelerate the car sputters and shakes does that mean replace the spark plugs and wires


Possibly, but other things can cause the same symptoms. If the check engine light is on, a scanner read of the computer will give you better clues that 'hip shooting' parts replacement can do. Possible things to look for--weak fuel pump, plugged fuel filter, water in the fuel, spark plugs and wiring, O2 sensor, and the list goes on.
