Don't make me watch a video. Just tell me the voltage while cranking.
If you have compression, fuel and spark, why doesn't it start? Something is still wrong, and you just haven't found it yet.
I videoed the cranking voltage as I didn’t have a helper handy and it seemed an easy way to communicate the result as I didn’t know exactly what you would be looking at.. looks like the voltage drop was 8.3 max. Also the truck does start, it just takes a while that is what I’m trying to resolve. I’ve been reading/learning about data streaming specifically TunerPro and will also have to get a ALDL cable. Any insight there might be helpful. Do I need the TunerPro RT version, is the Moates datalogger the way to go?
You can get TunerPro RT v5 and this ALDL cable. That's what most folks on GearheadEFI use for OBDI and can help with tuning/troubleshooting.
Replaced the ICM with a Delco unit. No better, maybe worse
