i have a 2003 6.0 powerstroke and it wasn't getting fuel to the fuel bowl. i replaced the HFCM on the frame rail and that fixed that but then i have raw fuel leaking out the exhaust tip and my passenger side i'm out of ideas. if it's a wide open injector or a copper ring or the ficm. the truck dies out after 10-45 seconds of running

 

Can you tell on the exhaust manifold which cylinder is leaking out fuel? Pulling and inspecting that injector would be a starting point.
