I really need help with my 1995 gmc sierra 350 5.7 L 4x4.... Occasionally my truck wont start.. It wont even try to turn over.. Its like its getting no spark... But the other times it will start right up.... On the times it doesnt start i noticed all warning lights and the ABS brake light dont come on, when i turn the key to the on possition... Im thinking i have a short somewhere or something... I need to go to work 2morrow and i dont really feel safe taking it out.. Any help would b greatly appreciated.. Thank you..
