Could be a number of things but if it was starting O.K. one minute and then started acting up, Crankshaft sensor, down by the air conditioning compressor, Cam sensor, behind the Power Steering filler upper.
Or also could be the fuel pump or fuel pump relay .
try checking your battery usually it is the lack of cold cranking amps
Only if the engine is not cranking. Otherwise the problem is engine related.
ud be looking at a broking t belt plus water pump
if it is cranking but wont start check for spark, fuel, air and compression.
may be a bad starter..... or if the engine is cranking with no start it could be the ignition wires
How do you know that it is your car?
I'm extremely sorry that I can't answer this, but i recommend you take the car to a garage, somehow.
check for spark. check for fuel pressure.
It wont start
Do the headlamps work while cranking the starter? If not focus on your battery and cables. Jump start the car and have the system tested before you throw more dollar bills at this problem; it could be the alternator but have it tested first.
Your car wont start. lol
I guess that the first would be that your car wont start. Otherwise look for slow cranking, spinning but not engaging the flywheel, grinding noises, or possibly a click but no turn but that is more often a battery connection issue or solenoid.
