Re: 86 S15 Jimmy ECM b fuse keeps blowing
Had that problem this weekend. The wiring harness from the fuel relay on the drivers side goes to the passenger side into the firewall under the heater and to the ecm. had a wire get grounded out and blow the fuse to the ecm which then leaves no power to the fuel pump relay. check the harness and make sure it is not pinched where it wraps around the tranny bellhousing
