I have a 2005 dodge big horn ram 3500. A red light came on just to the right of the speedometer. It was intermittant, then went solid. Th pickup now has no power and wont start. what should I do?
If it won't start, it's not the O2 sensor. That sensor isn't used until the engine warms up and the ECU goes into a closed loop condition. -- If it won't start you can't take it anywhere to get it scanned. If you can get a scanner, check the trouble codes and post them here. -- Try some starting fluid down the intake to see if it needs fuel or spark.
