My car cranks but won't start after replacing the battery

Hi, There can be several reasons a vehicle cranks and wont start after a jump start. I would start with checking the fuses, It may have blown a fuse during the jump start procedure. If you have a second key I would try that, it may have a problem with the vehicle recognizing the key. I would start with the two tips, thereafter if it does not solve the problem, I would have a qualified technician perform diagnostics. -Luis, Blu Automotive
