GM-GMC: 1990 GMC Sierra 1500, gmc sierra, pcm

Question
I have a 1990 GMC Sierra 1500 2wd with a 350 in it and it has no spark or no fuel! What can we do to fix this?

Answer
The first thing you can check is whether the little 'engine' picture shows up on the dash when you turn the key to the on position.  That will tell you whether the pcm is powering up or not.  If its not, start looking at your fuses etc for the pcm and see if you have a blow fuse or two.  Generally if you have no fuel or spark it is pcm related.
Hope this helps
