"No Communication” on every Control Module (ECM, TCM, BCM)What would cause my EVAP code, and my fuel pump relay to not get any power
Tells me there is likely a short, most likely in the lan bus, inspect everywhere you can see and look for a pinched or chewed wire, melted wires, wire rubbing on a surface and chaffing (common). lift everything you can that sits on something else and look for frayed wires
take a meter and check the lan bus ohm's on the obd port, I believe they should be 5 ohm's but just going off memory. testing that will tell you if there is a short or open circuit.
