Hi..
My Toyota Corona 1988 has stopped working
I was cleaning my car and didn't realize that radio was on, after the cleaning I tried to start the car and it wouldn't go, I got my brother to help me with a jump start but that didn't work, My car is a (Single Point Injector) I noticed that there was alot of petrol in the throttle body ALOT.. After doing some research on the internet i was believed that it was the Stater Motor and that the engine had flooded, I cleaned all spark plugs and Hoped that it would work again, but that didn't solve anything, After draining the oil there was alot of petrol in there, I topped it up but nothing happens.. Don't have much money to spend on it but need it to go... I just don't know what it is doing

When I tried to start the car, I put the headlights on and when I turned the ignition key the headlights would flicker and I can hear the engine barely turning over\
Please can someone help me?
