📋 Project Overview
This repository tracks all maintenance, repairs, and issues for the 2002 Chevy Express 3500. Each subfolder represents a specific issue or maintenance task with its own progress tracking.
Current Issues/Projects:
- Crank No Start - ✅ RESOLVED (distributor cap/rotor replacement)
- Power Steering Leak - 🔄 ACTIVE (fluid leak requiring periodic top-offs)
- Fuel Pressure Issue - 🔧 PARTS NEEDED (weak fuel pump identified, requires replacement)
Vehicle Specifications:
- Engine Oil: 5W-30, ~6 quarts with filter
- Transmission Fluid: DEXRON-III ATF
- Power Steering Fluid: DEXRON-III ATF
- Spark Plugs: 8x (exact type TBD - need VIN lookup)
- Fuel System: Electronic Fuel Injection (EFI), 55-62 PSI operating pressure
Maintenance History:
- 2026-03-21: Distributor cap and rotor replaced - Crank no-start resolved
- 2026-03-21: Power steering leak project initiated
- 2026-03-21: Fuel pressure issue diagnosed - weak fuel pump identified, replacement needed
Notes:
- Fuel pump confirmed weak - 37 PSI residual, requires 2 primes to reach 50 PSI
- Check valve is working fine (good pressure retention)
- Crankshaft position sensor (CKP) had history of issues on this vehicle
- Distributor corrosion is a recurring issue (~1x/year) on this van
- P0300 code - Random misfire code from crank no-start diagnosis (2026-03-20), should clear after fuel system repair
- Spark plugs - All 8 need replacement (matching set), low priority, pending fuel system repair first
