Kind of an unusual post for me, but I need some advice. What do y'all think is going on here? 2003 Ford F-350 Lariat 7.3L, been slowly getting worse and worse, and today in 35° weather I couldn't get her started today. Normally I have to plug her in around this temp and this was only after about 6 hours of not using a plug and after driving around. This is my work truck and so I need to get it fixed sooner rather than later. Any suggestions or advice is appreciated! I was thinking glow plugs? 🤷
