I’ve come along way on this vehicle. Just two weeks ago it would not crank and I had no spark. I was able to find a short in the wiring harness which was causing me to not have power to the ignition coil. now it will start and run. I have also installed a new perTronics ignition system in the distributor cap. Now I am back to the original problem which is that the vehicle cranks and runs for a short period of time but then starts to sputter and stall. It feels electrical to me but could be gas related. What are the most common problems for a situation such as this? It will idle endlessly in the driveway, and when it stalls, it immediately cranks and idles again. Thanks in advance!
