My uncle told me to always check the lift pump first on a 7.3 Powerstroke with a hard start

He said, 'It's never the injectors, kid, it's the fuel getting to them.' I ignored him for a month, replaced two injectors, and the problem came right back. A $90 pump from Napa fixed it. Anyone else have a stubborn old-timer who was annoyingly right?

My buddy's 7.3 had the exact same hard start and it was absolutely the injector o-rings failing. A lift pump is just a band-aid if your high pressure oil system is weak. How can you be sure the pump fixed it for good and didn't just mask a bigger drop in pressure? Those old engines have a lot of places for air to get in the fuel lines.

Saw a forum post where a guy chased hard starts for months before finding a cracked fuel bowl.
