ok this is exactly what happend for sure happend to me aslo...
first off under the hood is a voltage thing where if the batery gets to much voltage it shuts it down. re set the voltage thing..the injector problem is the first secondary injector wiring clip doesnt have the little metal peice holding it on.so it sometimes pops off..you have to take the intercooler off and the top part of the intake manifold off then plug the injector back in.that will fix the problem. also there is a 40amp fuse under the hood i dont know exactly what it is calle but it probibly blew and after replacing that putting the injector plug back on it will run fine
