You said you replaced the plugs - did you use the toyota platinum plugs? I found out the hard way that even the platinum plugs from bosch or any other kind of platinum plug just doesn't work right. Yes, they are more expensive from toyota, but they can make a difference in the way the engine runs.

Oxgen sensor. if it idles rough...sometimes close to stalling, but as soon as you give it gas she runs okay.... then it may be the oxygen sensor.

I HAVE 1985 TOYOTA CELICA SUPRA THAT WON'T STARTED. HAVE REPLACED SPARK PLUGS, ROTOR, DISTRIBUTOR CAP. WHAT CAN I DO?


Check your fuel delivery system, if the car is turning over and not starting you might have a bad fuel pump or fuel rail. Do you smell fuel when you try and start the engine? Or there is a longshot that the timing is off. Check the timing first.

84 celica supra doesnt get any power to the power windows. I have two repair books, but both books tell me nothing about were the fuze or relay is for the power windows.


My information is from a Haynes manual for toyota celica supra 1979-1992. the wiring diagram on page 12-31 shows that the "gauge" fuse controls the window power relay. There is also a 30A "power" circuit breaker that feeds power through the relay. The gauge fuse is located under a panel on the left side of the dash on 1982-1986 models. The power window relay is located under the driver's side dash in a "kick" panel fuse box on the left outboard sidewall. The 30A "power" circuit breaker could be located in one of the two aforementioned places, in a fuse block on the passenger's side kick panel, or there is a "specialty" fuse block under the hood next to the air flow meter---the manual isn't clear on the exact location. If you can find the 30A power c.b. you may be able to reset it by pulling it out and pushing a paper clip wire through the reset hole. Reinstall and see if you get power.

We can't find the fuel pump in the 1983 celica supra


It's inside the fuel tank. See if there's an access panel in the hatch and if not the tank has to be dropped to remove it.

1984 toyota surpa starts runs 10 sec. then dies


My first thought would be a bad sensor. Possibly crank shaft position sensor which provides spark to ignition. have you changed your fuel filter and cap and rotor on the distributor? Have you checked for any vacuum leaks? Is the check/service engine light on? You can test any sensor and RELAY with an ohmmeter in the ohm setting to see if there is continuity.
You can go to autozone.com and register for full free online repair manual for your supra.

Replace oil pump


Oil Pump is in the oil pan.. You would have to take the pan out. To get the pan out you either have to raise the motor up or remove crossmembers.

Missing engine


were the spark plug gaps set properly with feeler gauges if they were put in straight from packet they need to be set to correct gap which could cause miss firing or it is possible the leads were not put back on in correct order and probably a good idea to reset the timing if you do not have a timing light pop into mechanic its a 5min job an honest mechanic at worst would charge you $10 .00 to do timing this would make a huge difference when starting of a morning hope this helps thanks glenn

'84 Supra - Alt & Brake warning lights always on


It's possible that the voltage regulator is shot. I don't know whether the regulator is integrated into the alternator on your car, but a Toyota parts counter (call your dealership) can tell you, if you ask them for a new voltage regulator. They'll tell you if it's available separately or if it is part of the alternator.
