Please Help 2007 Silverado 1500 LT won't start...sometimes
Rickmag posted a question in Ask the GM TechnicianI have a 2007 V8 4.8 L Chevy Silverado 1500 LT and I turn the key to start it and sometimes nothing happens at all like the battery is dead (no dash lights, no anything). I try a few more times and nothing. Then I get back in it an hour later and it starts right up. Replaced Starter, battery is not an issue and problem still remains. Can anyone help?
2007 Silverado Knocking noise
Cocodrie1 posted a topic in 1999-2013 Silverado & Sierra 1500I have searched but found nothing similar to my situation. I apologize if I ovelrokked this topic I have a 2007 Silverado classic 5.3L V8 Flex Fuel 130K Miles. When I start my truck in the mornings or after sitting for a while it cranks and sounds fine. After a few minutes it develops a knocking sound (Very noticeable sound) that last for about 5 minutes. After 5 minutes it goes away and sounds fine. Its just odd that it takes 5 minutes or so for the knocking to start and after 5 or so more minutes to go away after that it sounds fine. Anybody got any ideas or suggestions where to start looking?
