Hello, I have a old Bronco with a wire management form Ford Racing (I think it was 85 mustang wire set up.) Im running a gt40 5.0 and have had good sucess for 2 years. Im having a problem now that Im wondering if I could get some ideas how to fix / trouble shoot. This problem for me is WEIRD! When first starting cold or hot it will not start. Than I tap the fuel shut off on the off position and it starts right up. While it it running I depress the fuel shut off switch to the on poisition and it will remain running fine. Now I will say that an electrical shop has messed with it in the spring of this year and the engine has been apart 3x this year. Everythings great (running now seamilgly great 45 minutes first time start this year). I thought it might be the fuel shut off switch, I replaced it with a new one same symption. While the engine a perfect 38 pounds fuel prussure, 50 pounds oil pressure. Any ideas?
Has any one ever heard of this happening?
Thanks, JOhn

What happens if you let the pump prime a few times before trying to crank it over?

The inertia switch thing makes no sense - there's gotta be something else going on.
