7.3 powerstroke slow first start
I'm sure this has probably been asked multiple times but all discussions I see seem to relate to glow plug issues and cold weather. My truck has been starting hard in the morning or after the truck has sat for about 10 hours or more at a time. Truck starts fine all day long otherwise. The weather is not cold and I've already replaced all the glow plugs and GPR so I can rule that out. I have also checked the HPOP for any exterior oil leaks and found nothing. This issue does not always happen but seems to be getting more frequent. Any help would be greatly appreciated!
