for engine starting problems, there are only few major components to check:the 2nd problem ,if the car was done a long drive or car engine turned off n started for few times, den the engine doesn't start anymore ..the "check engine" indicator doesn't go...even if turn the key also, nothing happen...but some high frequency sound will appear under the car if key turn to "on".

- check your starter, perhaps can add starter relay, or even check if the fuses are burning out (though they typically either work or they don't) or even the wiring around the fuse box area.
- check your spark plugs, see if they are fouled/covered in carbon, or even melted/thinned our spark tip/grooves
- battery, basic checking would be it's voltage, minimum also 11.5, ideally you'd want it to be between 12-12.5 volts. if you know workshops with more advanced meters, can also check it's cold crank ampere (CCA) to determine if the battery is in good condition or not. (doesn't matter if it is new battery, some batteries are just bad and their CCA drops very fast in just few months of usage)
alternator should not be a problem during cranking, as your battery is the one supplying power, and after engine is started (along with the alternator) only then the alternator takes over in supplying power as well as charging the battery for it's lost current due to the cranking.
