1987 GMC 350 TBI Problems, please help!
One more stupid question. When I pulled the instrument panel out, there is one instrument panel light right between the speedo and fuel gauge has a pretty good size black / green wire on it that runs to nowhere?

Ok folks, I am begging for help. I have an 87 GMC V1500 350 TBI that I cannot make any progress with. The problems started a few months ago when my son called and said it had quit on him while driving down the road. We drug it to the house and no spark at all, plenty of fuel. I pulled Code...- Barney313
