Too late to return. I had two days of fun in this car.

So we can assume whoever you bought it from was an As is sale and no warranty? To start a car you need spark, fuel, and air. How is the battery? Check all your connections. Can you hear the fuel pump prime?


If you replaced the crank sensor had your mechanic checked it for codes before you bought it? I would say he owes you a road call if he just guessed. Have him check for codes and start from there.


He tryed to check the codes but , after I replaced crankshaft sensor it dosent start at all I already order an original fuel pump I think if I raplace it, it will help, and I bought a new battery so it cant be it. My mechanics told me if the car wont start the codes wont go away.

You still can check the codes without the engine running. They will be stored in memory if you didn't disconnect the battery yet. If it is a hard fault it will still set a code just by cranking the engine even though you disconnected the battery.
