Default 99 F-250 electrical issue

Iíve got a 99 F-250 that I canít get to start it has no voltage to the inertia switch for the fuel pump.. sits there and cranks but wonít fire.. also when I turn the key on thereís a few relays that chatter in the under dash fuse box. Also the dome light relay clicks on and off unless you pull it.. if you pull it it all stops. And if you have the relay out and hold the unlock button down the dome lights come on and stay on as long as you have the button down.. any help is greatly appreciated

That’s what I’m wondering what would be the best way to go about checking that

What is the battery voltage. Check with the key off, then with the key on then while cranking.

Have good voltage. Just hooked up a scanner to it and I’m getting no response from the PCM. Is there anyway that I could have a ground issue and not a bad PCM or will the PCM still communicate with a ground issue. Where should I go from here

Also there are a few fuses that if I test with a test light the interior lights start to flash like I’m providing it a path.. maybe GEM module ?
