Did you put plenty of heat sinc grease on the TFI before you installed it. If not pull it and do that or it will fail again. By the way you were correct the inertia switch impact switch only turns off the fuel pumps in an accident the fuel will not just keep pumping out of the tank it has nothing to do with ignition. I am old school too you need to slow down your thoughts and focus on one at a time. When I get going I forget to punctuate also and even confuse myself when I proof read a post. Still working on that, go through alot of the qustions you have can be answered in the tech library, and probably alot you haven`t asked yet.
