Injector could be stuck open.

maybe check the voltages on the injectors too

hi guys.i hooked up a scanner to my gp and the only thing that comes up is short to fuel level sending unit.and that makes sense because my fuel gauge spikes and stays there.so i unplugged the sendingunit(thankyou gm for having a plate in the trunk to get at it)and my fuel gauge is still spiked.so i either have bad wires or the pcm is no good.where is the pcm ground wires located?because it also said the pcm may not be grounding properly.
let me know what you guys think.
thank you in advance

That's a big problem man! I think you should bring it to the repair shop of car. They are the one that is expert to it.
