Hello Everybody,

I am new to the forum and apologies if this has been answered already.

My Dad's Chevy Blazer 1995 SL 4.3l V6 Vortech is in our garage for about 2 years now and I would like to get it back on the road for him.
I have tried to look up the forum for an information regarding OBD and reading the trouble codes using the jump wire method but I can't find it and I am lost.

The computer is next to the engine under the hood,
16 pins on the OBD socket located on the left /driver side.
Pins active in the socket 2,3,5 ( top row ) 9,13,16 ( bottom row )

Which ones I should bridge to be able to read the flashing codes?
None of the nearest service garages are able to read the codes. Their scanners simply can't see the vehicle!
We are located in Europe.
Any help will be very much appreciated!
I will try to post some pictures as I am getting that beast back into its shape :-D
Thank you
Dom
