P0201 thru p0206 Codes.Runs great.
Have a 96 Cherokee that is popping P0201 through 6 codes for fuel inj circuit open.All 6 .Runs fine but check engine light is on so no inspection.This is my "pull behind the camper" jeep not the crawler.Checked grounds,resistances, etc.May be down to ECU.Any ideas or ECUs around?

I doubt all 6 injectors, circuit wires or PCM drivers all went bad at once, particularly if the motor runs fine.
You checked for proper voltage at the injector connectors, and ohmed out the other connector pin back to the PCM?
This might sound counter intuitive, but I've read of others fixing this problem by replacing the TPS. Might at least give it a cursory check...make sure it's resistance sweeps up smoothly with no dropouts or dead spots while you operate it by hand through its' range.
