My '89 Supra Turbo won't run, any troubleshooters?

08-29-2005, 11:10 PM

Thanks, I'll try that. I was thinking I might need a new O2 sensor -- but , like supragirl said, It would likely make it run more rich -- but since I now have my AFM replaced, things could be different now. I don't recall that a bad 02 could keep it from starting, but I could be wrong - maybe if it had a short in it, that would cause some serious problems, but I'm not too knowledgeable on emissions stuff.
I appreciate the input and answers, I'll update my troubleshooting as I go along. Maybe
you can help me out Supragirl, as you seem to know what you are talking about. And who said car stuff was only for guys, LOL. I respect a knowledgeable girl in the realm of vehicles and engines -- and you drive a supra to boot, you rock. I still hunting for that damn boost leak, but it's so tight in there around the turbo -- It must be the main intercooler hose on the bottom of the turbo. If I was smart (and not broke) then I'd be slapping a
hard pipe kit on there and be done with the worrying -- but I might have to improvise. Any ideas?

take it easy.

if its a money problem you can have any half decent exhaust shop build you a hard pipe set for about $200
and i think your 02 problelly fine it sounds to me like the iac valve ...check the plug in and the hose that runs to the cross pipe and then to the intake for any cracks...ive seen leaks in the iac hose system trip an afm code
