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.

sounds like ecm. car starts but when it switches over to run setting from cranking setting the cumputer ecu doent activate the run curcuits which may control your fuel injectors. check to see if engine has spark. remove one plug wire from spark plug put it close to the valve cover if you see an arc then you know that you have spark. then also go to fuel pump in tank and check voltage on the power wire if you have good voltage and the pump doesnt make any noise while ur cranking then it may be a fuel pump if the pump is making way to much noise then check the fuel pressure by hooking up a fuel pressure gauge. all test are to be done while someone cranks the engine. noid light for the injectors, disconnect on injector electical connetor connect the noid light to the wire that u just unplugged from the injector. the light will flash while u crank , once it goes to the run circut the light will either stay on which will shut off ur car or the light will stay off which will do the same. if the noid light did what I said when it went to the run circut then it is what controls your injectors...ecm good luck....daniel

Have you looked under the vehicle, usually near the seating area, check on both sides, if still unable to find, located the fuel tank and then trace the lines forward this should run you into the filter.

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.
