Diagnosing intermittent injector control circuit misfire on a 2003 Chevy 6.0L with prior parts swaps and limited diagnostic tools
No structured diagnostic workflow or centralized solution to systematically test injector circuits, interpret codes, and avoid replacing parts redundantly.

Workarounds Described
- Swapped injector pigtails from cylinder 3 to 5 to test circuit
- Replaced fuel rail with a spare to isolate issue
- Wiggled wiring harness while engine running hoping to affect misfire
- Used cheap injectors from previous owner as trial-and-error
Implied Software Gaps
- Structured diagnostic workflow that suggests specific tests (noid light, continuity, PCM pin voltage) based on code and live data patterns
- Component swap logging that automatically tracks which parts were moved and where, to identify circuit vs. injector faults
App Concept
MisfireGuard Pro
A mobile diagnostic assistant that guides users through step-by-step injector circuit troubleshooting. Integrates with OBD-II scanners to suggest targeted tests (noid light, wiring continuity, PCM pin checks) and logs repair history to prevent parts cannon approach.
Key Features
- Interactive diagnostic flow for specific engine codes (P0200)
- Component test guidance (noid light, multimeter, wiring diagrams)
- Repair history log with timestamp and part replacements
- Pinout diagrams for PCM connectors and injector harness
Target Users: DIY truck owners and small garage mechanics working on GM 6.0L and similar engines
Revenue Model: Freemium with $9.99 one-time fee per diagnostic guide, or $4.99/month subscription for unlimited access
