My truck lost power and has a rough idle. Got codes P0203 Injector circuit Open-Cylinder 3-------P2146 fuel injector group A supply voltage circuit/open-----same as p2146 but at the end it has "pending" also. Any help with how to fix this problem would be welcomed. This is my first posting, hope I'm in the right place.

Start by checking the plug connectors on the Valve covers. I doubt that your injector failed more likely the wiring harness (part of the Valve cover gasket) has failed.

or any box that connects to the injector connectors. With out a signature??

I checked both plug ins on the drivers side, no burnt places, both were tight. My truck has 157000 mls on it. thanks for your advise.

Made an appointment with local mech, Thanks for the help.

Local mechanic put electrical grease in the two plug ins at the drivers side of valve cover. Reset computer. Truck running fine now.

Glad you got your truck running. Sounds like it was more of a "Reset" that cured it than the grease on the connector.

Thanks, I feel the same way. I need to get a programmer that will clear DTCs.
