We replace the fuel pump and battery but doesnt wont to start. What can I do?
you need to tell us what the original problem was. just a no start? no cranking? are you just throwing parts at it and hoping it starts? does it have spark to the plugs? is it getting gas to the engine? did you do a compression test? but if you want me to guess I would say maybe the crank sensor is faulty.
I would say either diagnose it properly yourself or, if that is beyond your capabilities, take it to a shop that can.
If you want help.diagnosing what is wrong, you are.going to have to tell us a lot more about the car.
If you want to shotgun parts at the car, try replacing the crankshaft position sensor.
