Hello i have a 1994 s10 blazer tahoe lt has a 4.3L engine (W in the vin).
I just had a shop replace the injectors (spyder) and fuel lines (800.00).

The service engine soon light keeps coming on. I can't afford to keep taking in so thought i'd buy a code scanner and see if i can do this myself.

Not sure which scanner to get OBD1 i believe but not sure.
It has a plug on right side of drivers side under the steering wheel.
The plug is 2 rows of 6 (12 pin in all).

What scanner do you suggest?

I'm looking at this one: Equus 3120 Innova Diagnostic Code Scanner

I also need the ODBII as my brother has a 2000 Ford truck (sorry) lol

Thanks
Bobby

 

Your '94 is OBD I.

 

And you don't need a scanner, just a paperclip. Jumper pin A to pin B (top right-hand pins) together, then turn on ignition switch (do not start the vehicle).

Start counting the flashes. It will repeat each code three times, then move to the next. First code will be 12 (flash pause flash-flash) and last code will also be 12.

Cheapest scan tool ever!!

 

Especially if it came home from work!

 

The guy at auto zone said to do this and I didn't believe it. SO went to Advance and paid $30 pretty much giant book. Nice to have the book with the codes and such but BIG waste of $$.

 

thanks for the link to the codes

also thanks for the info on how to get the codes without a scanner.
