Hell newbie to the forum here. I am having problem with my 05 Sierra 1500. S Lea are replaced the starter and I had to replace the mission housing assembly which consisted of the cylinder that housing and a new Ignition switch. Put everything back together. Try to start to truck. It won't start, I have power. The battery showing twelve point five if I jump the starter with a screw driver it starts and stays running. But I can't get it start with the keys. Oh ya all fuses and relays are new as welll please help. Thank you all in advance!!!
