90 TR start problem

Car has been running great until I parked it the other nite. Came out the next day went to start it an it ran for about 30 seconds an quit tryed again about 2 hours later again the same thing. Have checked spark and fuel an both appear to be fine. Anybody run into this problem or have any suggestions on what to check next.

 

FUEL PUMP....CHECK ALSO SENSORS / SOLENOIDS

 

funny thing you say this. about a year and a half ago when i first bought my 90 TR, it did the same thing . after sitting for 10 minutes, i pumped the gas pedal around 5 times waited a minute and it started right up. i never had the problem again. i'm not sure if i gave it gas at start up and that caused the problem originally but i never give it gas at start up now as per previous owners advice. sorry i'm not much help, just thought i'd share that. good luck.

 

Sounds like an airflow problem. I would check the all the basic's first in the air intake system,starting with the air filter. Then move to the AUX air valves, possiable throttle plate adjustment,and cleaning(over time carbon and blowby gases/oil can build up on the trhottle plates closeing off the .003thou gap). Sometimes this is enough to keep the engine from starting on the first try. This is why on some cars you have to tap the gas inorder to get that extra bit of air into the engine. I would also rest the throttle plate gap or at least check it to make sure that it is still within spec. Then you could move to the Co adjustment screw on the airflowmeters. But this should be adjusted only if you have use of a gas analizer and have a good feel for adjusting the system.

Generaly speaking..when a car catches and then dies it is usually one of 2 things..too much fuel or not enough air. I think in your case as you have described it it seems to be an airflow issue.
