2JZGTE SC

Hi,
I think my fuel pump went on my 94 SC300. I have a 95 2JZGTE and I think I have over worked the stock fuel pump for a long time and it finally died.

DOES ANYONE KNOW IF A SUPRA FUEL PUMP CAN FIT IN AN SC300? Thanks

mine is a GTE fuel pump. Dont know if theres any extra modifications to make it fit as my Mech did it for me.

Yes it fits. I'm pretty sure there's a writeup on here about it but if not a lot of people run the TT denso or the Walboro pump

Fits like stock and the Denso is definitely an upgrade.
Make sure you do a new gasket or your car will stink forever. I FIPG'd mine just for extra protection.

Thanks for your feedback everyone, I hope the installation goes smoothly. Is it possible to change the pump with 2 gallons of gas left in the tank? Should I disconnect the battery?
Also does anyone have a good write up on how to change the pump, any help would be great.

Yes disconnecting the battery is a must and yes you can change with 2 gallons in the tank.

Future SC thank you so much for taking the time to put that write up on here that helped tremendously.

I had a big problem though, the lexus fuel pump has a wire harness that clips onto the top of the fuel pump. I bought a Supra TT fuel pump and that has two screw terminals on the top of the fuel pump (-/+). I'm not sure if I can cut the harness off and make my own connection on the new pump. I dont know if that would cause a spark and blow me up when I turned the car on though.

Also I checked the resistance on my current pump based on your SC diagram, and it read ok. So I am perplexed, becuase the ohm meter read the fuel pump correctly.

...At this point I am assuming I have a bad fuel pump ECU, what do you guys think???

ill tell you something funny, i did mine with like 10 gallons or more in the tak i took the pump off and i was like oh **** that is close it was an inch from the hole and to top it off i was on a driveway, if i was on flat ground that would have been all bad. DO THE 12V MOD OR UR CAR WILL NOT RUN. ok good luck

What he said^^, the tt pump will not operate with the factory fuel pump ecu. You have to do the 12 volt mod.
