Re: 97 sub blows fuse ecm b with fpump relay removed
OK, I just went out and looked at the PCM on my '98 Sub. There are only 4 big connectors to it and you said you disconnected 5?? Are you sure we're on the right page?
With the pump relay removed the problem is not downstream of the relay but could still be a chaffed power wire shorting to ground.
The 2 top plugs on the PCM are labled "white & black" on the unit itself. Are these 2 of the 5 plugs you disconnected? I could only find 4 on mine. The PCM is just fwd and at the same level as the underhood fuse block with cooling fins on the top of it.
