I have a 1986 GMC Jimmy with a 2.8 in it and 114365 miles on it. It died one day and would not start afterwards. We found out it kept blowing the ecm-b fuse everytime you tried to start it. We have replaced the ECM, the ignition module under the distributor, the fuel pump relay switch, and the electronic ignition module, as well as the fuel filter with all new parts but it is still blowing the fuse. The truck tries to start but is not getting any fuel. I am not even sure what the ecm-b fuse runs so Im not sure what else to do. Any help would be appreciated.
I have now donated to the forum by paypal
