Did I fry my FICM

my FICM has been giving me some issues lately. Sometimes the truck doesn`t want to start but I find if I plug it in and wait 15min it will start. Today I did not plug it in at work and when I went out after work the truck would turn over but not fully start up. I plugged it in. When I went to try the truck seemed to start up but then quickly died. Now the truck is completely dead. I have accessory and everything but when I turn to the key to start the truck it is completely dead. Absolutely no response. I tried boosting it to no avail. I put a new starter on the truck like 2 months ago. So I dont think it is that. I think I just fried my FICM. Any other input would be great. Thank you.

First off the FICM has nuthing to do with the starter working, it only controls injection.

You may ahve a bad starter solenoid, a issue with the ignition key or module or something as the starter fuze or relay blowing even the ignition relay.

Ive ran into instances where the wiring harness was bad and the truck wouldnt crank either. Grabbed the wiring harness and pulled and wiggled on it and the truck fired up. Something easy to check.
