[QUOTE=C-PHartley;2577091]The mechanical c 8.3 only needs fuel & air to run. If the fuel solenoid is held open it should start regardless of any fuse or electrical situation. I suspect a lack of fuel is the culprit.
Like He said- needs only fuel and air to run, I believe your Tach is signaled from your Alternator. Have someone visually check that the Fuel Solenoid Pulls when the Ign Key is turned on and stays in that position while trying to start it.
