13.6 volts is NOT a battery voltage, it reflects surface charge which is not real. A battery can only read up to 12.8 volts in and of itself. You may just have a bad battery. Let the car sit overnight (over 8 hrs.) with no starting or charging and check the voltage the next day, if anything less than like 12.3 volts the battery is a problem.
Injectors firing at 11.5 volts is worthless as well, they will fire lower than that but in no way will they be metering correctly and you cannot see that.
