John Loper II 12bc8111f5 docs: Complete documentation overhaul for all three issues
**PowerSteeringLeak:**
- Comprehensive README with diagnostic findings, theories, tools, parts estimates
- Added video resources for leak detection and repair
- Added step-by-step repair procedures for rack, pump, and line scenarios
- Organized with clear sections and status tracking

**CrankNoStart:**
- Added video resources for distributor replacement and diagnostics
- Added detailed step-by-step repair procedure (completed)
- Added parts used section with purchase details

**Overall:**
- All three folders now have consistent, comprehensive documentation
- All include: diagnostic process, theories, readings, parts/tools, video resources
- Ready for systematic maintenance tracking

2002 Chevy Express 3500 - Documentation Audit

Date: 2026-03-21 Purpose: Verify all three issue folders have complete documentation


CRANK NO START (CrankNoStart/)

Current Documentation Status: COMPREHENSIVE

What's Included:

  • Diagnostic process (priority order, common causes)
  • Initial symptoms and assessment
  • Theories tested (fuel, spark, compression, timing, ECM)
  • Diagnostic readings (45 PSI fuel, P0300 code, spark check results)
  • Root cause identified (broken distributor rotor spring)
  • Repair performed (cap, rotor replaced, cleaned housing)
  • Parts/tools needed (scanner, pressure gauge, spark tester)
  • Cost estimates (~$60-90 total)
  • Session timeline (2026-03-20 diagnosis, 2026-03-21 repair)
  • Lessons learned documented
  • Related notes (CKP history, distributor corrosion pattern)

Missing:

  • ⚠️ No YouTube/video references for distributor replacement
  • ⚠️ Could add more detailed step-by-step repair instructions

Recommendation: Keep as-is, minor additions optional


⚠️ POWER STEERING LEAK (PowerSteeringLeak/)

Current Documentation Status: GOOD BUT INCOMPLETE ⚠️

What's Included:

  • Diagnostic process (investigation plan, checklist)
  • Initial symptoms and assessment
  • Theories tested (rack seals, line connections, pump seals, reservoir)
  • Diagnostic readings (fluid level low, brown/tan color, contamination)
  • Root cause NOT YET IDENTIFIED (still investigating)
  • Repair performed (none yet - still in investigation phase)
  • Parts/tools needed (basic hand tools, UV dye kit, etc.)
  • Cost estimates (rack $200-400, pump $100-200, etc.)
  • Session timeline (2026-03-21 initiation, fluid correction)
  • Lessons learned (wrong fluid used, correct fluid identified)

Missing:

  • No specific diagnostic readings (no UV dye test results yet)
  • No step-by-step leak location procedure
  • No YouTube/video references for leak detection or rack/pump replacement
  • No detailed repair procedure once leak is found
  • No specific parts purchased status

Recommendation: ⚠️ Add diagnostic procedure details, video resources, and create "Repair Steps" section for when leak is located


FUEL PRESSURE ISSUE (FuelPressureIssue/)

Current Documentation Status: COMPREHENSIVE

What's Included:

  • Diagnostic process (3 tests: pressure retention, 30-min wait, running pressure)
  • Initial symptoms and assessment
  • Theories tested (weak pump, clogged filter, check valve, regulator)
  • Diagnostic readings (37 PSI residual, 48 PSI 1st prime, 50 PSI 2nd prime, 53-54 PSI idle)
  • Root cause identified (weak fuel pump, clogged fuel filter)
  • Repair performed (none yet - parts ordered)
  • Parts/tools needed (filter #88915445, disconnect tool, jack stands, etc.)
  • Parts purchased status (filter ordered from eBay, ~$8)
  • Cost estimates (filter $8-20, pump $150-400)
  • Session timeline (2026-03-21 diagnosis complete)
  • Installation guides with YouTube and written links
  • Detailed step-by-step repair procedures for both filter and pump
  • Success criteria and verification steps
  • Lessons learned (may have caused original no-start)
  • Related notes (P0300 code, spark plugs pending)

Missing:

  • ⚠️ Could add more video resources for fuel pump replacement
  • ⚠️ Could add specific part numbers for aftermarket fuel pumps

Recommendation: Keep as-is, minor additions optional


📊 OVERALL ASSESSMENT

Status:

  • CrankNoStart: Complete - ready to phase out
  • FuelPressureIssue: Complete - actively used
  • PowerSteeringLeak: ⚠️ Good foundation, needs diagnostic details and repair procedures

Priority Actions:

  1. Add YouTube/video links to PowerSteeringLeak for leak detection and repair
  2. Create detailed "When Leak Found" repair procedure section in PowerSteeringLeak
  3. Consider adding more specific diagnostic test procedures to PowerSteeringLeak

Next Steps:

  • Update PowerSteeringLeak/README.md with video resources and detailed procedures
  • Commit changes to Gitea
  • Consider phasing out 2002-Chevy-Express-Diagnosis and 2002-Chevy-Express-PowerSteering folders after verification
