I
own a 2004 gmc 1500 sierra v6 with 127000 miles. I recently repaired/changed right/rear o2censor.I also changed plugs/wires/air filter/gas filter. After about 200 miles check engin light comes on, I did scan and pulled a p2539 code /where do I go from here?

I think you need to read those codes.P codes don't run over the 1800 range.

My scanner does read p2539, apparently it is a gm generic code that has something to do with fuel pressure. But I don't know if it is fuel tank pressure or fuel injector pressure or whatever and this is where im stuck. I hope its something like a gas cap
