Just want to logic check a no-start diagnosis before I head out, to make sure I'm not forgetting anything. fackin car /ubbthreads/images/graemlins/mad.gif
General:
- car was running fine when put in storage. Took out of storage, battery, fuel, & oil all acceptable.
- Drove ~15m with no issues at all, not very spirited driving, temp is fine. Cruising at 3000rpm, it sputters/dies in a fairly calm fashion with no nasty noises or smoke.
- Afterword will crank strong, just no start. Got a sputter ONCE.
- Fairly confident electrical is OK. ECU cel at "on" check, ECU is nice, alt & battery strong. Fuel pump/MPI OK.
Troubleshoot:
- OIL: looks like a little water contamination from sitting but acceptable
- AIR: everything looks connected, couplers etc. GM MAF & elec. connections look fine on inspection
- FUEL: 37PSI at AFPR. Didn't test individual injectors yet (that seems unlikely to me, more of a "after it's towed" step)
- TIMING: check belt, rotate to check cams line up, eyeball crank lineup
- SPARK: going to pull each plug and check by sparking against head. Inspect plugs.
- COMPRESSION: last test before tow, need to tow it today if no luck.
