Checking a distributor
I posted earlier about my truck going through distributor caps. Well This one lasted about three weeks and the truck died on the highway. Can't see anything wrong with the cap, but I installed a used one to try it and the truck fired right up. I now changed the coil, ignition module and pick up coil. New wires and plugs going in tomorrow. What is the best way to check the distributor for wear without removing it ?
