I’m willing to bet you have an ignition issue. Try reinstalling your 123 distributor with cylinder 1 at TDC and the valves closed. Then rotate the distributor until the green light comes on. What you are doing here is syncing the engine and the electronic ignition. Once you have that set bolt the distributor down. Don’t worry about where the pointer is pointing on the pulley. All of your curve adjustments are made using the 123 app. If you need assistance just give us a shout. There is a lot of 123 experience here.
