i have a 90 supra with the 1jz. The car wont start. usually every morning before i go to work i will start it and let it run for 5 to 10 min. The car fires up on the first try. Then the other day i went and fire it up and started for 5 sec the car sputter and then cut off and after that never got the car to start agian. I never mess with anything before when the car was running. I check for fuel, spark, bad coil and the igniter and everything works ( I even relpace with good working 2jz parts and still the same).I check if i have power to the ecu and i do. Check for blow fuse and there is none. Timing looks likes its correct also but i could be wrong. Could timing just jump on these 1jz. What about coolent temp sensor if that bad could it cause the car not to start. Dose the 1jz have a cps if do where is it located. Could the tps and map sensor or crank sensor cause this kind problem. Also what is the chance that the ecu just went bad. If i keep on cranking the car after a few try it sound like its trying to combust. I'm clueless at this point any suggestion will be very helpful.
