More ignition issues on the dart

Years ago I had a similar problem with a Volare. After several tries of trying to start it by releasing the key it finally started. After the engine warmed up and the ammeter died down I drove it home. I was tired and the family was too so off to bed. Next morning I grabbed an old rusty ECU, a phillips, and a jumper wire with alligator clips and tested it. Varoom! Installed it. Bought a new ECU and swapped it in. Kept the good old ECU in the glove box along with a phillips and a 7/16 wrench. Never had to use it.
