check your wires underneat that run back to rear of vehicle, sometimes when the both mounts rust through the body come down on the wires and grounds them out
The fuel pump is shorting out and that is why the ecm fuse is blowing .Disconnect the the fuel pump and try it again,if the fuse blow's again then it is not the fuel pump.
The Blazer was discontinued from production after the 2005 model year, and was replaced by the TrailBlazer. That being said, you have a short to ground somewhere in the circuit.
Wrong amp of fuse
Check for recalls first then I would estimate either an overload on the circuit, bad wiring harness between particular fuse and the component it powers, or a loose wire.
There seems to be a short to ground in the wiring somewhere.
then there is a short some where!
Does the obd2 plug work? allot of the time it can be joined with the cigarette lighter. Check that it could be an issue. If not I would think the ecm may be shorting out?
It being an American vehicle
NO.. It will not.
My first thought is that the fuel pump is going bad and is drawing too many amps, second would be a wire grounding against metal.
There is a short somewhere in the circuit.
A short in the wiring.
