There are splices in the harness on the ground side of the injectors. They have a tendancy to get corroded. I found mine by stripping all the tape off the harness and following the wire down. The splice was near where the wire for the AC compressor comes out. I would unwrap the harness staring at the PCM untill you find the splice. Just remember to seal it all back up with some quality electrical tape when you are done. i did not have to remove the harness from the engine to complete this repair.
