An injector is just a coil and one moving part, you can't really kill it or fry it with the car voltage, even if you apply direct battery voltage to it, it won't fry, its impedance cannot got below 11.4 ohms, so the current will never go above a certain amount, about 1 amp, so no matter how you connect it to the car, it cannot fry. If you connected it to a different power source with higher voltage, maybe, but I don't see any way the 12-14V power from a car could fry it. Besides, it is not a semiconductor, it can't burn with the right voltage, electronics are different. An injector is not electronics, it's just an electrical valve. I could see semiconductors burn even with the right voltage for no reason once you connect them, but I've never seen a coil burn when you connect it to the right voltage. My system could have not killed the injectors.
