It sparks amazingly when held to the block, it was the first thing to check before doing all other effort. There is no oil on the water. I bought it with not functioning fuel pump and I found the issue after I installed the fuel pump. Actually I installed another one just to be sure this is not the reason. So, head gasket might be the only option left and I will need to take the head off to check? Would this be possible with this compression? I am too tempted to get rid of this head as I have a GE one and this is the reason I was hesitating doing it. I was hoping for an easy project.

All leads are new and all spark plugs are new as well as the distributor cap. Indeed, pulling the cable off the cylinder 1 doesn't change the work of the engine, while pulling any off the others would nearly stall it (two cylinders left). Swapping spark plugs or leads always keeps the first not firing. The spark plug on cylinder 1 turns wet and black. The one on #2 is rather black with a bit of brown, the others are rather brown Cold compression test reads 11.7 on #1 and 12 on the rest. Warm compression shouldn't be as far from this to the point to fully not ignite cylinder one.

Hello guys, I am trying to build love to a good condition AE86 with 4AC and keep it original for the moment. There is not logical issue however and being out of ideas I am reaching out for help. The cylinder one refuses to work, no matter what. There is spark, a good one. Distributor revised. There is fuel. Tried with different carb from working 4ac. There is good compression on all 4 (12). Valves have been adjusted 3 times and are in spec. The car is running smooth on the other 4 otherwise, starts first try. Runs rich, I assume due to the not burned fuel in cylinder 1. I am really out of ideas what to do next. Anyone had a similar problem and ideas for testing please?
