Here is step by step.. You need to do two things find out of you have fuel or.. spark.. The easy way is to turn over key but dint start car just listen to see if you can hear the fuel pump powering up.. IF YOU HEAR NOTHING 99% TIME YOUR FUEL pump... Other ks foul spark plugs check plugssee if got spark check YouTube how to.. If spark is good then you have to check engine codes but more likely if she was running well it be a fuel pump or those spark plugs that you just cant reach kist let go.. Hey aloy shops dont bother changing one plug if it hard place tl reach! If it run well alit time i seen new plug but one behind never changed!!!! Fual pump problems most likely
Check for good spark ,if ok check fuel pressure and flow, if pressure is low replace fuel pump, if flow is low replace fuel filter and check fuel regulator for leak back.

Better check your owners manual.

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.
