DTC codes p0231, 069e

[avwrench60]

2009 Silverado 1500 Ext cab 5.3l

Check engine light on (will not clear)
Can clear the dtc codes 231 fuel pump secondary circuit voltage low, but it returns.
Now the truck runs intermittently as does the fuel pump.

any suggestions?

I did clean the ground point under drivers door g300.

thanks

First off, this is in the wrong section, should be moved to the gas engine section.

Secondly, provided it's under warranty, take it to the dealer.
