The truck will start fine and run good when it is cold. I will drive it for a while and turn it off, when I try to start it again there is no fuel to the injectors. The fuel pump comes on, but no fuel from the injectors. It seems to me that it is something electrical heating up and failing. Does anyone know what could be causing this? I have replaced the fuel pump, rebuilt the throttle body replacing the fuel pressure regulator inside the throttle body, and checked the fuel pump relay with no luck. I read on another thread that people were having a similar intermittent problem and it was the ignition coil. Could the ignition coil affect fuel to the injectors?

if there is no spark/then the fuel injection does not work. it can be a ignition module or coil scan for codes first see if any come up.
