CEL on 1991 Truck
Hi
Hope you can help. For some reason the search function will not work from the computer at work. On my way in this morning my CEL came on. How do you pull the codes from a 1991 V-6, 5speed? As far as I know it has no OBD. I believe there is a port in the engine bay that reads diagnostic on the cap. I need to find out whats wrong before I cause a greater problem while driving home.
Thanks

You can jumper TE1 and E1 pins and the CEL will flash giving you the trouble codes. Check the manual to see what the code means. Link to online manual below.
