So... You've downloaded a fan-made engine. One thing I already notice that's out of the ordinary is that there are ten wires connected in the distributor while there are TWELVE total wires, consider removing the 2 extra ignition wires and see if that works.

thanks!

edit: i did it, but it still won't start, it happens to me with every fanmade car
