My boss said to check the lift pump first, saved me a whole day
Had a 6.7 Powerstroke with a no-start. I was ready to pull the injectors. My boss, old guy named Frank, just said 'check the lift pump pressure before you do anything stupid.' He was right. It was at 2 psi, not 55. Bad pump. Fixed it in an hour. Anyone else have a boss with that one go-to piece of advice that always works?
My uncle ignored a seasoned mechanic and blew his engine on a road trip. Cost him three grand and a ruined vacation. Sometimes free advice is the most valuable thing you can get.
