my injectors will not fire. ive checked the voltage and they have power12v i have three sets. one set if from a known working car which i put in after i tried on mine and it started right up so i know they are not stuck. Its not the ecu i have tried once again three. two stocks and my power fc one of the stock was known working and once again i put it back into a running car and it worked. my main relay clicks and my fuel pump turns on so i dont think its that. so the crank angle sensor? i dont have another one so before i go out and buy one to try it i figured i would see if anyone else had any idea's? i did test my CAS with a mutimeter and it was in specs. by the way this all started when i pulled my wiring harness back to the firwall. ive checked everything MANY times. ANY HELP PLEASE

Just incase anyone has the same problem check out your wiring haness and make sure you continuity from the main relay to the injectors (the constant 12v wire on the injectors, mine were black and yellow and should be the same on all s5 cant say if its the same on s4) i had a broken wire in the harness.
