Starter Question
The other day I went to start my 7.3 and it turned over very slowly, second attempt and finely started had to go on a 30-35 mile errand and when I got back turned it off and it fired right up no problem. I have been thinking for some time that it has been taking longer and longer for it to start. After I let the truck sit all night I checked them and they were both at 12.56 volts I am going to check them again tomorrow to see if I drops. It will be the second day of it sitting to see if there is a drain.
As far as the HPOP goes which bolt do I take out to check it? I think it is the one that I have to remove with an allen?

Are saying that the batteries are showing 12.56v? If so how old are they? Try taking the batteries to a shop and have them load tested or you could check each of the cells with a meter to see if you have a bad cell.

Yes if I unhook both of them they both show about 12.5v. I do not know how old they are they were in the truck when I bought it about three years ago. I bought it from a dealer and I thought they were new but I can't find a date on them, they are motorcraft batteries 750 cca.

Ok, make sure the water level is good in the cells, if not use distilled water. Definitely check each if the cells they should all read about 2v. If you have a autozone near you, ask them to perform a battery load test to see if they are strong enough, and you may also want to have your altenator tested as well. What year is the truck and how many miles are on it?

Sounds like you've got at least one bad battery. As stated in previous posts, take the batteries out and get them tested. That's exactly how my truck acted when one of my batteries went out.

It could be something simple, check all your connections including grounds. The starter could be shot drawing too many amps. disconnect one battery at a time and check the voltage at each as you have them disconnected. If one is a lot lower than the rest you have a bad battery. Your voltage at the starter while cranking should stay above 9.6 volts.

It sounds like the starter solenoid/relay or the starter is at fault to me. If the solenoid/relay had a burnt spot on its contactor it could have caused the symptoms you described. How old is the starter?
