I have replaced the starter, new battery, pressure regulator, ignition switch, new exhaust, spark plugs and a electrical wire. After the car sits overnight, I try to start the car and it cranks and cranks and it doesnt start. After a few times of this the battery drains. Please help! I am a single mom of two boys and I desperately need this car to be fixed!

When it doesn't start, have you checked for spark and proper fuel pressure to the engine? It sounds like the fuel pressure is weak.

Yes, there is a spark and the mechanic did check the pressure and fuel. Its a Ok. This is so crazy! Mechanic fixed a wire to a sensor and change the fuel plugs. The two days the car was there, everytime they started the car it started right up no problems. I went to pick it up and it started up. I woke up today went to start it and it wouldnt!

Check the fuel injector and pump relays and fuses.
