I had my water pump replaced then my car was misfiring on cylinder six, so I took it to a shop they did a decarbonization treatment (they check engine light was also coming on when accelerating). I got it back and two days later the car started and shut off immediately, wouldn't rev even when I pressed the gas. That happened twice then it wouldn't start at all. The battery is fully charged. It doesn't make a cranking sound or anything, nothing happens when I turn the key.

Hi Sunny.
first check the fault codes for proper diagnosis,if u don't have scanner, you can make fast trouble shooting.
-first check battery condition.
-when you turn the ignition key engine does not turn and u don't hear any clicking noise from starter,problem can be from starter solenoid or its cable,ground,ignition switch,when you hear clicking and engine does not turn problem can be from the starter internal contact,or the wires and ground also.
-remove the spark plugs try to turn the engine by handle with its socket from crank pulley over miss fire can flood the cylinder with fuel that stops the engine from turning.
-then miss fire problem must be solved detecting by scanner which cylinder miss firing,checking ignition coils,injectors,engine compression.

They solved the misfire with the decarbonization. Now the car started then shut off right away then it started again and shut off right away although I tried to give it gas. Battery is fully charged, when it started and then shut off all the lights came on and everything and then the third time I tried to start it nothing happened it didn't crank or anything.
