You need to narrow down the problem. When you say it won't turn on, I'm assuming it turns over but it won't start. If that's the case, make sure you have a good fully charged battery, check battery voltage, it should be minimum 12.4. If battery is ok, spray some quick start in the throttle body to see if it'll start for a bit, if it does, it means it's not getting fuel past the injectors. Check fuel filter,check fuel pressure. If fuel is ok, check spark on spark plugs.
