I have a 1995 Impala SS 5.7L LT1. 140K miles, strong running, but occasionally will not start. After it sits for for a while it will start. It always cranks fine but wont fire. Sometimes it tries to fire. There seems to be an intermittant electrical short. Sometimes the electronic dash display does not act right and becomes dim during these no start attempts. I have a brand new battery. Starter was removed and checked ok, although starter has always turned a little slow. Clock light on radio now stays on when key is off. I dont think the radio clock light should stay on.
Any help would be greatly appreciated. Thanks
