Question for anybody who wants to through some ideas..
If I start my truck up in the cool mornings it normally starts fine. After work yesterday afternoon it was warmer started fine drove about 20miles and went inside a store for maybe 10min. Come back turned the key and it dragged to start... almost like battery was weak. New alt, new bat, wires will get upgraded soon but my question is this I suspect heat causing this. So what the heck is dragging? Is it the starter or something more major? The starter fairly new from oreilly and It doesn't have a heat shield but is that really my issue or do you think it can be the electrical components? I know it's hard with out seeing the truck in person but I've notice this from time to time if I try to start the truck after it's a pretty warm day. Normally if I let it sit to cool off everytime it starts fine
