I’m have trouble with my c4 I has 4 working injectors I don’t to much about corvettes but the driver side four injectors don’t have and voltage and we’ve taken it to different people and have had no luck in it I’m not trying to put more money into it and to keep having the same problem we’ve changed the injectors tps and map sensors new plugs wires and new distributor from bottom up rotor and all the car turns on and drivers just drives rough
If one side has power and the other doesn't, then it's most like a fuse or open wire. The +12 comes right from the two fuses as seen below. The ECM then fires them by grounding the injectors.
