danfleet1 -> ECM B (5/21/2007 12:44:11 PM)

Ok, I'm a fleet man who deals with mostly Fords(shoot me later). 1992 Chev.G20 van 5.7 ltr. Fuse panel, every time you put a fuse in the panel marked ECM B it blows. No problem with ECM 1 fuse. We have the whole harness stripped looking for burned wires, it started with another mechacic jumping off the vehicle then thinking he had a fuel problem when he was getting no fuel to the TBI. We are now cleaning every ground, checked the ECM, no problem. Does the ECM B deal with the battery due to constant power(hot at all times). ECM 1 is (hot in start or run). It is the only Chevrolet I have in this School District Fleet, and would like to keep it. Thanks, Dan
