Well I couldn't tell if it was the ignition switch or starter. So I tried out the starter, great price compared to autozones. It's starts up way better. However it turned out to be the ignition switch. When I crank the truck all my lights turn on but the truck won't start till the 2nd or 3rd crank still.
