Default Can't get rid of PO200 code

Any ideals? I've OHM the wires, check the connections, trace the wires back to the PCM. Everything seems fine. But still getting that code. WTF??? Running out of answers. Just throw some advice at me.

on the c100 connector there are 2 pink wires, one is for the tranny, one is for the injectors, make sure they are both getting power cuz i forget what is what.... then check ur fuses, if the car still runs (maybe runnin a lil rough) the fuse could very well be blown. i had this same problem recently.

I will check the c100 connector and see if there is power there. I put a NOID lite on each injector and the lite would flash off and on, so I figuered I had
12v, and the ground, that the driver in the PCM puts out. So I think it's getting it's 12v from the fuse box. Maybe the drivers in the PCM are going bad?
