2019 GMC 2500HD Duramax with 127,000 miles. FPC module went out about 4 weeks ago. It still starts occasionally and may run for 1 day or 7 days before not starting again. Part # 13558813 still on backorder. I'm on list at dealer I bought truck from but number 8 on list. Dug deep enough online and found one in Canada. Had to locate a friend in Canada to order for me and have delivered to their home. Then they will ship to me. Probably be another couple weeks before it arrives. Praying it will work. Can't believe GM can't get these parts since it looks like it's been a problem for over a year or multiple years.
