John Loper II 0a2d660494 docs: Update Fuel Pressure Issue - Root cause is failing battery, not fuel system 
- README.md: Marked Fuel Pressure Issue as RESOLVED (battery replacement needed)
- FuelPressureIssue/README.md: Updated to reflect battery as sole root cause
- FuelPressureIssue/progress.md: Added battery replacement steps, updated history

The van wouldn't start when battery was weak due to voltage sag preventing fuel pump from building proper pressure. When battery is charged, fuel pump builds full pressure immediately. No fuel pump or filter replacement needed.
