no the car stays running when i kept spray the starting fluid in the throttlebody. and nothing happens when i try to open the throttle when starting. i still think its a fueling problem. i know its not my pump. i took it out and test it. When i disconnect the fuel return from the engine, and...

Okay well the water temp sensor is connected but there no water in it. im just testing right now. 1) I have a jza70 ecu, harness. 2) It flashes rapidly. okay and what do i do to make the ecu think that ? i will make a video for you guys

weird ? mines is connected. but what does water temp sensor got to do with running?

yes i check for codes, showed no codes.and YES im getting 12v AT the pump too. i just took the tank and check the pump and its pumping great. yes i check if the pump running after the engine dies,and it does.. i seriously need help so bad.

well when i check the volts on the ecu on FP pin 16 i only get 10.83 volts. so it should be pumping. because today i took out the feed line from the dampener and i jump FP and +B on the diagnoses plug. and a lot fuel came out but it is enough is my question??and shouldn't it still be running...

it ran a bit longer like a 2 secs but still cuts and dies

yes but only when i jump FP and +B. but when i dont jump them the fuel pump turns on when i start the engine n turns off after the engine shuts off?

okay i grounded that green for the bodyside same thing! you think its my fuel pump? i means it pumping alot gas out the feed line. but is it enough??

yeah i hear click off and on. but why is that bro? well i grounded it from the engine side and nothing there so imma try the bodyside now.

yes they are. bypass you mean by jumping the 2 big wires together n the 2 little wires together on the relay?

okay do i take out the wire from the plug and ground it to the body ? because i did that and same thing happen.

are you talking about taking out the FP yellow wire from the ecu and connected to the black/orange wire?

okay so yeah that is my problem here bro. im only getting 12v on the FP pin 16 only when i crank the engine.?? what should i do for this step to make sure its always 12v??thanks hey guys we all here for help. cant we all get along lol. but i love you guys though. thanks for the help very much

okay just sprayed starting fluid in the throttle body. im doing this by myself so yeah im spraying it and then starting it. it took awhile cranking it before it started but it ran alot longer than it did before. no not the fc. the FP 16 gets 12v only when i crank the engine and when it dies 2...

how do i check that? thanks

nope all stock.the O2 sensor isnt on tho. barely got the swap done and this is whats happening. i check my ignitor. map ecu on another supra 1jz it worked great. how do i check my cam sensors if there good. but when i disconnect them the same thing happen. try disconnectin the tps too and...

did you ever got it running

so what is causing this problem bro? no one can seem to help me. i mean my wiring has to be right or it be throwing codes right?????

okay on that diagram i got 12v on plug T on 1 and 2 and 12 and 13. but on plug X i get 12v on pin 14 but on the FP the fuel pump relay i dont get 12v til i start the car??? is this right

yes my check engine light works, it blinks rapidly. it use to blink code 31 air flow meter. but swap out a new map sensor and it went away. my timing is on. i check like 20 times. how do i check on the IAT and ISCV? haha and that music was my party rocker music when my car runs.
