Why do I have to step on the go peddal to start my truck?

I have a 2002 Ford F-450 with 88-k miles was a repo off a local bank and was dead when I bought it. We just installed a new a starter and new batteries, truck turns over great but WILL NOT start unless I step down just alittle on the go peddal. Same thing every single time we start it.

Have any ideas???

Truck has ZERO codes and even run the buzz/ contribution test and everything shows to be good and in working order.

If you have a buddy with a similar year truck you could try swapping them and see what it does in his truck.
