Had an issue starting my truck this morning when it was about 45 degrees outside
I have 2 new batteries and new starter

Ok so i replaced my GPR and i found out today my dually is a California emissions truck and after replacing the GPR the truck was already warm and i couldnt tell an immediate difference after replacing it so am i going to have to wait until its gets cold again to see if it fixed the problem or what and i tested the old GPR and it would click when i grounded it out so im confused any help would be much appreciated
Thanks
