I am in SC. We had our first real cold night last week in the 20sC. I went out the next morning. And my 7.3 was turning over slow. But never started. It popped and sputtered a few times but never fired up. I figured it was the POS Autozone batterries. They have given me issues in the past. And had been replaced a few times. They were holding 12.5v. When I was on the starter it dropped to 8.5v. I checked for good grounds. Or any other cable issues. And used jumper cables to isolate the cables all together. No issues found. So instead of replacing em again. I got me 2 new Interstate 65 series. It turned over slow still. But with a grinding noises. I slipped under the truck. And found that my starter was prying itself apart again. About 5 years ago the bolt on the starter motor broke. And it has done it again. So I got me new starter. And its spinning over fast as hell. But still no start. I apparently have a multi level problem here. I went to check the fuel bowl for fuel. And when I loosened the lid it sprayed out. So I obviously have good fuel pressure. I had a spare cam sensor. So I threw that in. And still no start. I pulled the ICP. It was kinda wet looking. But I didn't clean it off. And it still didn't start. Something is keeping it from firing the injectors. I am at a loss now. Where should I look next? I did the UCVH replacement several months ago. So that should be good. Also I plugged it in for the first time in its life(SC/FL truck) to see if was the GPs. Its back near 70s again now. Whats odd is that it happened on the coldest day of the year. Or just Murphy's law? It started great with no issues. Its like it was weather related. It literally broke in my driveway. I lost the pages(206-212) to my fuses/relay in the manual. Is there a relay or fuse I need to check?
