Since you said the black smoke problem started when you upgraded your fuel pump and black smoke should mean you are running rich/unburnt fuel, than your fuel pressure may be one of your problems. The other thing about the timing seems to be a problem, because if your timing is not going higher than 10 degrees with the spout connector in, than that is a problem. When the car won't crank it may be because it is flooded so try pressing the gas to the floor and see if it will start. Once you get it started make sure your timing is working first. If the black smoke is still there once you get the timing working than try and reduce the fuel pressure. I know new people hate the see people pointing them to the search feature, but there is alot of old threads you can find if you search "black smoke" or "fuel pressure" and there is alot of info on tuning a EFI car, so that may be more help than I am. There is a thread under the !!! TECH ARTICLES !!! at the top of the forum on setting the timing that may be help with making sure the timing is working. Good luck and welcome to the forum.
