Laramie gone loco

Got an 04 Laramie 5.7 Hemi that’s suddenly got several things acting screwy- ie brake and marker lights stay on after vehicle is turned off, hard to start - like it’s not getting enough fuel but fuel pump is working just fine, and now it won’t shift past third gear-fourth gear won’t engage.
Motor has 90k actual. All of this started when front end was rebuilt about a month ago. My buddy thinks it’s the pcm -I’m not so sure. Anybody else run into a problem like this?

I always found good times in Laramie. It is a university town and lots of great music comes through on the Interstate. The good acts are on their way to somewhere else, so they play on week nights usually. Some great western swing bands bring out the loco in the locals. Watch out for tourons.

Load check the battery as well seems to be the first order of business.
put a amp meter on the battery when everthing is turned off.
look at all the wires around the front end check for green wires, check all the connectors.
This crap can cause a drinking problem.

First make sure your battery is good, then make sure the battery terminals are clean and making good contact and alternator is putting out. Then find all your wiring harness ground connections and make sure they are all clean and in good shape. Bad grounds will cause multiple faults and just having your froont end done I suspect shop may not have replaced one properly or moved it or bumped it and it is causing issues. Bad grounds cause multiple faults all over the system
