So, I just bought this truck and when you go to crank the truck and turn the key to the run position it’s trying to crank and takes like 6 or 7 tries before it starts. I have taken the ignition switch out to illuminate the ignition lock and it still does it. I have tried putting it in neutral and it will work how it’s supposed to, but you can’t turn it to the start position. Would you maybe have a solution on things to check? The previous owner said he changed the ignition housing and that’s when it apparently started doing it. Please help. I don’t want to burn my starter up.

It sounds like the fuel pump might be getting weak, but I would change out the fuel filter first to see if that makes a difference. Here are two guides that can help with instructions and the location of the fuel filter for your truck in the images below:
