I have several problems with my truck but I will start with one. It will no longer start. It was running poorly and, it may need a new fuel pump but at this moment, the fuel pump relay is not actuating when I turn the key on. There is no power at pins D and F in the fuel pump relay connector with the ignition on. I can cause the relay to actuate manually by applying 12V to pins D and F but it does not actuate when installed. Does that mean I need to replace the ECM…or is there another option? Thanks for any help.

First thing i would check would be the ECM Fuse itself.
Post back below and let me know what you found.
