Hello I have just purchased a 1976 109 Ute with a 2.25 petrol engine, it had been sat idle under some trees for 7 years. It turns over and most things seem okay but I have no spark out of the coil. I have had the coil tested and it is fine and even got a new lead from the coil to the distributor cap. It is receiving power from a wire coming from the loom which is on the positive and another wire off the dizzy cap which is on the negative side but still no spark?

Can anyone help me? Is there a wire missing?? or have I got my wires wrong??
