try this gives you a paper clip way to do it.
ALDL OBD1 OBD cable OBDI OBD2 engine codes

 

thanks alot 01 but the reason i bought this truck is to stay away from computers

 

READ THE POST - You watch for how many times the check engine light blinks. It will blink in a certain series. Count the blinks and write them down. The different codes will be seperated by a long blink.


Cycle the key on and off three times. Leave it on the third time. Count the number of flashes the check engine light gives you. These will be the error codes. It will be a series of flashes with a small pause between numbers. If memory serves me right 12 is the start test code and 55 is the end code. We need the numbers in between.

 

i will see what i come up with in the AM hours

 

you can also do the paperclip if you read the whole thing and it will make the cel blink and you can look up codes etc it has it all on there

Since we are looking at the connector pins, it should be mentioned here that a quick method to see which trouble code or codes are being set in your cars ECM is to jumper the A and B pins of the 12 pin ALDL OBD1 connector with a paper clip. While the car is off, sitting still, turn the ignition key forward while this jumper is in place. Do not start the car. The Service Engine Soon ( SES ) light will flash in a repeating sequence, telling which trouble codes have been set in the ECM. A service manual for your year car will have a chart outlining what each trouble code stands for, or this Trouble Code website can be of help. This paper clip method will tell you the trouble code or codes set in your ECM, but it will not tell you what conditions the trouble code is being set under, or let you clear the trouble codes on the fly, as the ALDL cable and PC setup will.
