I have a 1998 3500, with the 5.7v-8, and fought electrical problems for eight months now. i believe it is a problem within the chevy van, because a lot of people complain about blown fuses. my fuse was the ecm-b fuse as well, and after cleaning all the grounds and bat. connections, starter connections, and disabling the a/c circuit, on the advice of another poor van owner i replaced the ignition coil. six months so far, and no problems. this might help you as well. mine did not have any visable problems, but he was persistant, so i did it. good luck

2000 Chevy Express keeps blowing ECM-B fuse


you may need a new computer module. you can check for shorts by identifying where the computer module is and following the wires to your fuse box. this may take some time to do. also check your fuse box and make sure it is in good condition and has a cover, no rust, etc. best bet is to get a chilton's repair manual for your vehicle at a local autoparts store. about 28 bucks. especially if you need to do this on your own. this will help give you the correct procedures for identifying and fixing things.

If it "keeps" blowing the ECM fuse, it is because you "KEEP" replacing the fuse without diagnosing and repairing the reason the fuse is blown.
