Ok today i went and talked to my neighbor, he is an older guy who recently retired and sold his diesel shop after 30 years. He told me that he didn't feel the p1316 code or uvch was associated with my truck just dying while going down the road(ford tech said it can if entire plug is backed out, losing entire bank, it was). He said typically it will run bad but not die?? Actually he got me so confused explaining that the 7.3 has so much electrically that could go wrong, wiring harnesses etc. What I found interesting was, that he said even though my RPM gauge would move while cranking the engine over doesn't necessarily mean the CPS is good? He said almost always the CPS was swapped out and often that was the problem. He also said It didn't matter if the CPS had 5,000 miles on it or 150,000 miles on it, he would always check it. Basically it's the default troubleshooting for the 7.3. He also recommended not spraying starting fluid or wd40 into the intake. In the end he basically told me to try the CPS and for the $29 I would at the very least have a back up in the glove box if that wasnt the problem.
Also to have it buzzed tested, which could take an hour or several hours trying to isolate the problem.
Additionally, I went to the new owner and spoke to him as well, he didn't think the CPS was bad, but thought the IDM, ICP or IPR was bad. Need to do a buzz test but he also said it could be an hour or several hours to find problerm. He also didnt recommend spraying starting fluid into intake.
Im more confused than ever now. I know that it is getting fuel to the bowl, and voltage is good.
