Difficult Starting after sitting

[Phoenix of Fury]

I'm having trouble starting my Comanche after it sits for around 24 hours or so. After I get it started the first time, it will start again with no problems for the next day or so. But after it sits for over a day, it takes a long, long time to start. I've killed the battery once trying to get it to turn over.

 

I'm not sure if it's a CPS problem, because of the fact that it starts with no hesitation after it has already started once. Is it a possible fuel pump on it's way out?

I had a very simular problem on a 97 chevy 1 ton with a sb it would do the same thing I thought I had a fuel pressure problem but turneed otu in the end it was the pump don't know if this helps ya but I would lean that way IMO
