Have a 2019 Chevy 2500 hd , sometimes when I turn the key on to start , have nothing. When I turn the key off and on and take it out of park , all my dash lights come on than it will start. Any help?
Remove the battery cable at the battery. Clean the cable ends and the battery posts using baking soda and water and a stiff brush. Continue until it stops bubbling. Rinse well with fresh water.
When reconnecting the cables to the battery make sure the are tight. Lace a large gob of Vaseline over the cable end and battery post.
