No Cold Start

I have a 2002 F-250, and I recently started having a hard time starting in the morning. I replaced the GPR, but still pretty tough to start the first time in the day. Any help would be greatly appreciated!

Is the new GPR working properly?
How are the GPs?
UVCH and connectors?
Batteries? Connections?

Well I checked the voltage coming off the GPR and it was .3V. So I changed the relay. It starts fine after it warms up.

No, it started this morning. It doesn't just fire right up in the morning, it turns a few times before it turns over. I had it running this morning at about 9, and I went to start it about 3, and now it just don't start.

Would the UVCH cause this?

This is a really dumb question, but, if I got 3-4 good 2 second cranks from my batteries, is it possible that the cranks are not good enough to start? The reason Im asking is because like I said earlier I got a good 3 or 4 cranks or until my batteries were dead, then I went out and charged my batteries and the damn truck fired right up...

Yea, it has to crank at a certain speed before the PCM will allow it to fire.
