I suggest you stop using your MacBook immediately, disconnect the battery and charger until you can clean the logic board. It's a typical story... 1) liquid spill 2) panic 2) Oh, it works! Panic over. 3) it stops working after 2-3 weeks 4) by this time permanently energised power supply areas on the logic board are corroded beyond repair You need to clean your logic board immediately. Good wash in hot water and 24h drying should be OK.

When reinserting the keyboard ribbon cable, make sure you push it in all the way (two plastic tools are helpful - one to push it down flat, the other to coax it all the way in).

I usually use a piece of sticky transparent office tape and stick it over the flat cable a bit further away from the mating part then pull on it. There is no better way to force the flat cable into a stiff connector without damaging the fragile cable.
