I got the new ECM and unfortunately the truck still has the same issue. Still trying to figure it out... The only active code is SPN 168 FMI 1 SAE- Battery potential (Voltage) Data valid but below normal operational range - Most severe level. From component #128. I can't find any info on that code or what component 128 is.

What is the fuel pressure and oil showing while cranking?... and after, as it dies?.

What is the ecm voltage while cranking?>,.. and after, when it dies?.

Also, what does the Insite software show for active and inactive faults instead of some after-garbage SPN-type code reader?.
