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 if spark is ok, check crankshaft sensor
