I have a 2012 freightliner cast radio and I'm having a hard time getting the truck to start I replace the starter charged the batteries but she will still not start the motor isn't locked up so what could be rhe problem
Sounds like Fuel issue. But first I’d check fuses. What engine Cummins or dd? Gotta see if you’re getting fuel pressure first. If it’s cranking it was never the batteries or starter
