obd_reader.py: - Mode 22 plumbing: ELM.mode22() sends a 16-bit PID request, parses both positive (62 ..) and negative (7F 22 NRC) responses. - --ford runs a small TENTATIVE table of community-sourced Ford 6.0 PIDs (ICP/IPR/FICM/EBP/EOT). All printed with raw bytes for verification. - --pid XXXX probes a single PID and prints multiple candidate decodings (u8, u16, mV, temp, duty) so we can eyeball the right scaling. - --watch [N] streams ATRV + module voltage (PID 0142) for N seconds. Designed for capturing voltage sag during cranking. - --scan AAAA-BBBB brute-force scans Mode-22 PIDs with --scan-log PATH for output. Uses fast ELM timing (ATAT2, ATST19) for ~3.5 PIDs/sec. diagnostics/2026-06-29-no-start/: - Captured cranking voltage trace, full Mode-22 scan (1000-14FF -> 46 hits), and a session writeup. Working hypothesis: not batteries, not fuel -- ICP / FICM / CMP. FICM meter test still owed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

6.0 POWER STROKE -- NO-START QUICK TRIAGE
|
|
================================================================
|
|
|
|
NO-CODE no-start basics to check by hand on a 6.0:
|
|
1. BATTERIES: both must be strong. Low voltage -> FICM won't boost ->
|
|
no injector fire. Load-test both; ~12.5V+ at rest, hold while cranking.
|
|
2. FICM voltage while cranking (~48V). The #1 6.0 cold no-start cause.
|
|
3. ICP (Injection Control Pressure): needs ~500 psi to fire. Big leaks =
|
|
STC fitting, oil rail O-rings, high-pressure oil hoses.
|
|
4. FUEL: lift pump (HFCM) priming, fuel filters, water-in-fuel.
|
|
5. CMP/CKP sensors (see codes above).
|
|
6. Glow plugs/relay if it's cold out (won't stop start, but hard start).
|
|
|
|
|
|
Done. (Re-run any time; codes persist until cleared.)
