I have a 91 SBC 350 TBI with small square coil just outside the dizzy. Trying to start I have no spark. The coil has 4 wires on 2 plugs: plug 1 - Pink for power, white for tacho. Plug 2 - red wire and white wire (if I remember right). How can I check if the coil or the dizzy module is faulty? PLEASE HELP!
