my daughter has a Dodge Van B 1500 . the van stalled and they thought it was out of gas… put in fuel and still won’t start… changed the fuel pump because the pump wouldn’t hum so they changed that… still nothing… it is saying something about "no BUS " when put on the computer it says it is unable to establish a connection… does anyone have any ideas???
A No Bus message means the computers/modules aren’t communicating with each other. This could be caused from a poor connection between the computers/modules, or a circuit that has a blown fuse. The first thing to check for is a blown fuse that may have knocked out one of these communication components.
