car suddenly wont start - never ran great anyway, esp. cold, now cranks, but won't st

[rjSupra]

Hey Cre:

Thanks for jumping in again. To clarify, did you mean that the 02 sensor won't prohibit the ECU from detecting proper levels in the exhaust to set, uh things it does like fuel mixture, air etc etc... (therefore crap mpg and maybe cranky starting in the cold perhaps with the 'wrong' settings for fuel / air)
or did you mean 'No' to the thought that if the coils were shot it wouldn't run at all.
This guy was not a Supra expert, but works on cars before as a mechanic and does know the Supra somewhat (like that it's an inline 6 3.0 liter etc...)
Perhaps he does not know there were 3 ignition coils in this car. He also did not seem to know what an igniter is in it. But he did state a shot 02 sensor that is triggering OBD means the correct levels can't be achieved for all engine temps, and this would account for not running great, perhaps bad starting cold etc...

Thanks again!
