Hi there, welcome to the forum.
You will need to be more specific about the car and the problem before we can help.
Which engine is in the car?
A no start situation in petrol engines has only two causes: lack of fuel or lack of spark. No fuel = empty fuel tank, faulty fuel pump or relay, blocked fuel filter, faulty fuel pressure regulator, etc. No spark = faulty coil packs, faulty crank position sensor, faulty DME/relay, too many others to mention.
Without the ability to do some basic diagnosis, it is very difficult to pinpoint the problem. Best you get the car to a reputable workshop to diagnose the cause of the problem.
If you would disclose your locations, other members can recommend reputable workshops that won't rip you off just because you are female. They generally rip everybody off equally and don't discriminate on gender.:rollsmile:
