Car
not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.
To
confirm the problem, the basic troubleshooting is required.
