1jz is not starting!

sao1 · 11-22-2005, 02:27 AM

Hello,
Im such a newbie with supras. im sorry in advance to ask dumb questions. But two days ago my brother took out the car and drove the car just fine. When i went to start the car again, after about 4 hours, the car doesn't want to start.

The car would just crank and i would get not fuel and no spark!!!!!!!!

The fuel injectors is getting battery power and so are the coils, but still now spark and fuel.

I want to test out the fuel pump, but i don't know where it is on the car. And where is the igniter on the supra. Is there a crank sensor on the supra? And where? And which wire is the B+ for the automatic 1JZ ECU? So i can see if we are getting power to the ecu.

Sorry for all the questions, and thanks for looking.

fuel pump in the tank, mkIII has an access panel under the mat for the spare, 3 screws ur there. back probe it, while u key up with a test light. bad igniters r fairly comon on 7m, not sure about 1jz.(pricey items though). also about 3 relays r related to ur fuel pump. fi relay, main fi relay, pump relay, curcuit opening relay. my advice, if u couldnt find the fuel pump, take it to a shop
