car running about 3 weeks ago after replacing fuel sensor(dealer)...now car won't start...engine cranks but won't go all the way...battery is good

 

retired97, are you looking to fix this vehicle yourself or would you be willing to let your dealership take a look at the vehicle? They should be able to diagnose the vehicle and from there you can repair the vehicle yourself with a better idea as to what the problem is. I hope this helps you.
