Replaced GPR, Not Cold Starting still, battery light always on

[FactorySlow]

Hi guys, new to this forum. Ive been searching this forum trying to get some answers on why my truck is constantly not starting if it sits for over 4 hours.
So I have been searching through the forums and reading peoples posts with the similar issues.
Here is what my truck does. Walk out in the morning to go to school/work turn the key wait to start comes on for about 10 seconds. Turn the key and all it will do is crank and crank and crank. Even if i plug it in it wont start. So in order for me to get it started I give her a little sniff of either (YESSS I KNOW EITHER= GRENADE). But thats the only way the truck will start when it is cold. Please don't respond telling me how bad either is, I know how bad it is and am fully aware of the consequences. once it starts it smokes blue until warm. Once up to temp I can shut it off and it will fire right back up, but if the truck sits for longer the 4-5 hours it will not start.
So yesterday I swung by autozone and picked up a new GPR installed it and ever since I installed it my idiot battery light is constantly on and has not gone off yet. Also my truck still does not start cold with the new GPR.

My question is: What should I check next?
- glowplugs?
- GPR wired wrong? (that would be silly if I did)

My truck is a 95 PSD, 5 Speed, with 213k miles.

Thanks in advance guys!!
