Recharged the car battery, dashboard lights all on, starter motor producing the starting sound. Engine not starting. After seeing this question, I cleaned the solenoid brushes and at the first turn of the key, the engine starts for half a second and stops. Because of continuously trying to start the car, the battery seems to be going down. Tried pushing the car to start it, but it didn't.
My dad says the problem may be because no petrol is reaching the engine (which may be true because it's been more than a week since I've started the car). Plus, one engine bore is worn out because of which engine oil hits the spark plug, causing misfire. It's been more than six months since I've given it for servicing (spark plug changed) and I use the car only about twice a month.
Is the solution to find the tube that brings petrol to the engine and pour some petrol into it (I hear people do it when air gets into the pipe)?
p.s: Also, as a secondary question I'd like to know a neutral opinion of how often should a person give a car for servicing (car more than a decade old) when it has a misfiring problem?
