I think you should read Captain hooks first post again

 

With all due respect, A "dead" or "poisoned" converter is the result of another problem, not the root cause. If the converter is subjected to excessive HC levels for an extended period of time, it will destroy the converter. Replacing the converter without repairing the root cause, (incorrect fuel mixture) will result in the replacement converter failing as well. This link explains the possible causes and what effect they have on the four emission gasses: http://www.autoshop101.com/forms/h56.pdf

 

What does your engine look like?

This is CMFI. It was by far the most common engine used in 1995 S/T series vehicles. There were two different computer control systems used on this engine:





This is CSFI. Very few, (late production) were installed in 1995 S/T series vehicles. It has a totally different computer control system:

 

I have the one in the first picture

 

And here's a picture of my OBD

 

Sorry, don't know why the picture is upside down

 

Ok, CMFI, with OBD 1.5 computer controls. This is probably why you couldn't get the scan tool to communicate with it. It requires special software in the scan tool.

 

I went to an auto store and theirs wouldn't read it either. Is there somewhere specific I have to get it checked at?

 

OBDI systems, (mid 1995 and older) you can jumper 2 pins in the port to retrieve the DTC's. The DTC's on your vehicle must be retrieved with a scan tool. You'll need to find a shop that has a scan tool that will communicate with your system. Call around to local shops and explain what you have. Your system is inbetween OBDI and OBDII. It has an OBDII, (1996 and newer) type port under the dash, but the vehicle is not fully OBDII compliant with emission requirements for 1996 vehicles. Wish I had better news, but it is what it is

 

Well thank you for your help. Hopefully I.can get it fixed. So my dad can quit bugging me about selling it. I haven't even got to use the 4x4 on it yet haha.
