Every once in a while when I start my truck none of the dash gauges work, if I shut it off and restart it they work. Everything runs there just is nothing, even the speedometer doesn't work.
Any ideas?

My truck did that when new. It hasn't done it in a LONG time. There have been quite a few trucks that have done it. I think it might be a sticking ignition switch or something. Sorry I can't be of more help.

A new service calibration has been released to correct this condition. Reprogram the IPC using the new service calibration, which was available from Techline starting November 3, 2003 on the TIS2000 version 11.5 or later. This calibration is an electronic calibration and is not available from GMSPO.

Some have also found one of the two batteries defective.
