Blinking service engine light
I have a 4.3 2000 blazer today check engine light came on blinking and had a rough idle gas gauge bouncing all over... Any ideas went to pull codes and scanner couldn't find a connection at auto zone any idea on how to fix that as well? Picture just for attention, any help is appreciated.

I think the Check Engine lite blinks a bit as the ECM sets the codes into memory.
Not sure what you mean by could not find a connection at Autozone??...could not find the OBDII connector under the steering wheel, or could not find an Autozone with a GM OBDII cable/connector? If you could not find the OBDII connector under the dash, then drop the trim panel under the steering column and see if the OBDII connector is there. |
If i'm not mistaken, a flashing CEL light is bad...
The guys at AZ couldn't find the OBD port??? |
Most likely it's a P0300 misfire. Class A misfire that can cause damage to the engine or catalytic convertor
|
The guys at AZ found the port but couldn't make a connection, I later found a blown fuse going to get the codes pull later today.
