I have a 2010 2275rli with a 6.2L i'm having low voltage issues and need help. I have replaced both batteries, and my alternator and the battery switch. When I turn the battery switch on and turn the key low voltage alarm goes off guage reads under 10 volts When I start it runs real lean like its not getting enough fuel If I put it in gear an run at some speed it will read 13.5 volts and run good. Any ideas where to look
