apparently i forgot to hit the post message button
anyway i recently tried to scan a 1996 gmc pickup and kept coming up with vehicle not responding and yes the key was on i had even started the truck to make sure. my question is what would cause this to happen
the truck has 250,000 miles and has a 5.0 liter engine if that makes any difference

Check for power on pin 16 of the datalink connector. That would be the orange wire on the back of the connector. If you don't have power, check the aux power fuse 7 25amp in the IP fuse block.
If you have power, try a different scanner to rule out a problem with your equipment.

I'm not sure what type of scanner you are using, but you should at least have a generic OBDII mode that would work. Wouldn't pull much info than codes, but it would tell you if it will communicate. Even if you have a parts store try to scan it and they can't communicate that would confirm the trouble is in the vehicle and not the scanner. Try as DS said and look for power at pin 16.
