I have replaced the following: fuel pump, lines, filter, all relays, injectors, fuses, and completely rebuilt the throttle body. Still no fuel getting to the injectors, also replaced the cap rotor and ign. Module, use a noid light tester and get no pulse. Please help. I have spent too much but love my truck.

Hello, I'm Danny.

All of the output drivers are controlled by the ECM. It sound like this is what your having trouble with. If you want to send me the VIN number vehicle-identification-number from your truck I can find what ECM it came equipped with to help you find a replacement. I've attached a picture below of the ECM location on your truck. Hope this helps and thanks for using 2CarPros.
