My 1991 Chevy Suburban keeps blowing the ECMb fuse. Last Saturday the car started and ran for a minute or two. It stalled when I turned on the windshield washer. I couldn't get it started again, but the starter did continue to turn when I turned the key. I replaced the fuse but it blew again on the first attempt to start the car. I checked the distributor and replaced it and the rotor because two of the posts were spinning. A new fuse and it started. I let it run in the driveway for about 10 minutes. I turned the car off and tried to start it again and the fuse blew again. Called a local shop that specializes in electrical work. They told me it sounds like a short between the ignition switch and the fuse. I asked about using a stronger fuse just to avoid a tow charge and drive it in. They told me it would be fine. It has since blown 15 and 20 amp fuses (rated for 10amp). I've checked all the wires I can reach, both under the dash and under the hood. I don't see anything worn. Any ideas anyone? I have very little experience working under the hood other than changing a belt or the oil. Thanks in advance.
