Ok. So here is what I got. 1985 GSL-SE 13b. I Rebuilt custom street port, 750cc injectors. all brand new ignition, nothing fancy, and it won't start. I tried to pull start it but nothing. It backfires a lot and even more when I push the gas. But it will not run. The exhaust warmed up like its running. Here is a short clip. It dies when I put the clutch in. I have checked timing a dozen times ask words are hooked up and vacuum hoses. When the timing mark is at the pin the arrow points to the fire wall. But make a full rotation of the crank shaft or e-shaft and t points to radiator. so any suggestions would be awesome!

 

I say the distributor is not set right.
