[QUOTE="lucheski, post: 16029520, member: 45286"] I disconnected the PCM, still have short to ground. 0 ohms of resistance testing from the power (left) side of F26 Fuse to the engine block. I am going to test the short using the PCM connector itself so I know which circuit has the short to ground, should save time, I will update I also tested 5 of the 8 the COPS harness connectors for shorts I am showing 10 - 11 Mega ohm resistance between positive and negative at the COP connectors is that normal? I don't think that's my short since 10 Mega ohm resistance is pretty high and fuse block is showing 0 ohms resistance. Key was off [/QUOTE]
