Platform recipes (4)

• The 7.3 longevity package: the known wear points that strand or scare owners are all cheap.preventive fixes (modes fm-73-up-pipe-leak / fm-73-turbo-pedestal / fm-73-ebpv-stick / fm-73-fuel-bowl-leak)
• Cold-start system service (modes fm-73-glow-plug-system / fm-73-uvch-harness): HEUI needs glow assist below ~40F, and the chain fails link by link - plugs, the single heavy relay, and the under-valve-cover harness connectors
• Camshaft position sensor replacement for THE classic 7.3 failure (mode fm-73-cps-failure): heat-cycled CPS stalls the truck dead, kills the tach and can leave it restart-locked until it cools
• HEUI oil-side diagnosis and repair (modes fm-73-hpop-wear / fm-73-ipr-valve / fm-73-injector-orings): hard or no-start HOT with ok cranking speed is a high-pressure-oil story
