6.0 starting issue
 

I have an 04 6.0L that won't start when it's cold. It hits on a couple of cylinders it sounds like. Once it runs it starts fine after that. Mods consist of sinister deletes, sinister blue spring kit, SCT programmer. I'm throwing a code per cylinder sayin injection pressure low. This just started yesterday. Any help/advice is greatly appreciated

you need to do a leak test on the high press. oil system.

It's gettin a new icp sensor right now ill keep you guys updated when I get it back

Icp didn't fix it.. FICM voltage goes from 46 to 14.7 when trying to start it.. Is this bad?

14.7 is a dead FICM, it should never ever go below 46volts.......you can have the FICm repaired and it will be better then a new one, check out FICM Repair, they are a sponsor hear.

Okay thanks

Good luck! :c:
