1986 Ford F150: What controls fuel injector pulse..ignition module

This answer was rated:

I have a 1986 Ford F150, 5.0 EFI. What controls fuel injector pulse. We have replaced fuel pump, ignition module and the computer. It won't start. There is no signal to injectors. What do I need to try or do next?
The PCM or powertrain control module controls the injector pulse width,you need to check the wire and connectors for pushed out pins or broken wires.
