911 Carrera (1986) Won't Start |
https://forums.pelicanparts.com/porsche-911-technical-forum/1193179-911-carrera-1986-wont-start.html |
Clarify crank/no-crank; 3.2 pump does not necessarily audibly run before cranking; DME relay is an early branch, not a final diagnosis. |
Hitting rev limiter after refresh |
https://forums.pelicanparts.com/porsche-911-technical-forum/1192933-hitting-rev-limiter-after-refresh.html |
Distinguish true rev limit from tach error, reference-sensor gap, fuel delivery, ignition, and chip coding; repeatability across load matters. |
Crank position sensor |
https://forums.pelicanparts.com/911-engine-rebuilding-forum/1193176-crank-position-sensor.html |
Speed/reference connector order and sensor condition are common post-engine-work traps; degraded shielding/insulation is suspect. |
Wire harness |
https://forums.pelicanparts.com/911-engine-rebuilding-forum/1193047-wire-harness.html |
Photograph, tag, and verify connector pins before depinning; previous repairs make existing pin order untrustworthy. |
More HP from 3.2 |
https://forums.pelicanparts.com/911-engine-rebuilding-forum/1186399-more-hp-3-2-a.html |
Ask power target, budget, and use case; healthy 3.2 engines have limited cheap internal gains; rod bolts and matched build combinations matter. |
3.2ss Deck Height |
https://forums.pelicanparts.com/911-engine-rebuilding-forum/1192052-3-2ss-deck-height.html |
Measure real chamber/dome/deck values; compression, squish, fuel, and piston-to-valve clearance are linked risk decisions. |
How To Use Forum Advice In Answers
- Summarize forum advice in your own words. Do not copy long posts.
- Cite the thread title or URL when it materially supports the answer.
- Label forum-derived material as practical field evidence, not factory specification.
- Prefer threads with a final repair outcome. If the thread is unresolved, say so.
- Convert anecdotes into tests: what to measure, what result means, and what branch follows.
- When forum advice conflicts with factory data, use the forum post as a hypothesis and resolve the conflict with measurement.
High-Value Pelican-Derived Heuristics
- On 3.2 Motronic no-starts, first clarify
cranksvsno crank; owners often say no-start for both. - Do not condemn the fuel pump only because it is not heard with key on. Check DME relay outputs, cranking behavior, and fuel pressure.
- After engine removal or clutch work, speed/reference sensor connector order, air gap, and damaged insulation deserve early attention.
- A true software rev limiter is consistent. Load-sensitive breakup or tach mismatch points elsewhere.
- Verify tach accuracy before accepting a reported low rev limit.
- Before depinning any old harness connector, take photos, tag wires, and verify against a diagram or trusted pin map.
- For performance 3.2 builds, define the target before parts selection. Chip/exhaust gains are limited; larger changes require a matched engine, induction, exhaust, and tuning package.
- Do not rely on advertised compression or piston specs alone. Measure the engine parts in hand.
