Have started this truck before but it has been a couple of years. Previous owner installed a push-button starter. It turns over but no start.
Headlights work
Nothing else happens.
Nothing when I turn the key
No instrument engaged
Is this a wiring issue? Fuse? Cable?

Brand new battery

 

Mark, I moved your post to the Pre-97 section since you have a 91 era truck.

Sounds to me like an ignition or fuel pump issue when you use the Start Button. Check to see if you have spark and look for fuel delivery.

If NOTHING happens when you turn the key, it sounds like the previous owner bypassed that when the Start Button was installed.
