I have a 97 nissan pickup that won't start. I was driving down the road and it just stop. I had it towed home and appeared to being getting fuel but once home check for spark, none, I change wires dist cap and rotor, and still no spark. check relays and fuses. nothing it cranks but apsolutly not spark. could it be that little coil on the side of the distributor? there is 12.6 volts at the distrubur cap on th inside. any help would be deeply appreciated. The truck has 286000 mile but was running super when my trans mission went out. thank you
