pcm reset?

03 f350 7.3L


I pulled the PCM keep alive fuse by mistake while checking the instrument cluster fuse. The truck started for a second after that then died. When the key is turned there's random clicking, cd appears to go through a cycle, guages hop, drop then the truck appears to have no electrical power. Would pulling that fuse cause this? If so is there a reset process? Any input would be helpful. thanks

Disconnecting the batteries is the same thing as pulling that fuse.

In other words, it's not the PCM.

Thanks.

Any suggestions on what happened?

Truck's been having some issues with the interior lights/ radio working right but other than that it was fine prior to touching the fuses.

Again it started fine, ran about two seconds then something shut it down.
When the key is turned, there's nothing but random/ very quick relay clicks at the panel, cd going through a cycle and it's acting as if the batteries are dead but they have a full charge and terminals are clean.

Could be a wide number of things, from a bad ground to a bad GEM.

Thanks, it ended up being a bad under hood connector.

It's odd how things like that happen at the exact moment something somewhat related is touched. I'm just glad it wasn't directly related to anything I did.
