I have checked all fuses, relay and can hear fuel pump start it's strong trying to start but get no gas! My brother has sprayed starting fluid in the tb and it runs as long as you keep the fluid spraying. So any ideas on what else it could be? I just got done with a ge to gte swap and am running n/a fuel pump.

can you smell fuel coming out of the tail pipe?? did you change your fuel pump resistor pack, and injector resistor pack??? not sure if they'll stop your injectors from firing but i'm pretty sure there different.

The injector resistor pack can stop the injectors from squirting in fuel. I would check for a voltage readout at the injectors. The resistor pack has a single 12 volt feed coming in and 3 outputs with a 12 volt resisted current. The 3 outputs the drive two injectors each.

What exactly did you do for the conversion? Im assuming that you converted to GTE electronics correct? We have to know what exactly you did to help diagnose the problem.
yes, it's a true jdm engine and ecu. i dont believe i swapped to the turbo resistor pack... is there one i could just go buy? i think i've lost it in my mess of a garage....

you can see the 'injector resistor pack' on the far left(drivers side) and 'fuel pump relay' /resistor pack on the pass side. i think there different not 100% sure though. when i went na-t, so basically the same swap as far as electronic.. i changed both.

You didn't change and of the injector wiring did you? (hope not)
I would try to find it and put it in and that should solve the issue. With out it, there is no power going to the injectors thus the ECU can fire them....
If you cant find it, then pretty much any injector resistor pack(s) will work as long as its wired in correctly. You'ed be better off finding one from a supra though as it should be plug & play.... What ever you do, dont try to power the injectors with out the resistor pack. You will more then likely fry the injector drive transistors in the ECU if you do so.

Oh BTW, The fuel pump resister (one on right side fender) wont make a differance as to which one you have there. They are the same for both GE and GTE cars...

not sure what you saying but... i changed to the gte injector resistor because i read that the ge injectors were high impedance and gte injectors were low impendance. or vice-versa. either way i changed them and it started no probs. but maybe it didn't make a diff....
edit
ohh i change the injectors and wiring but i'd say its the 'swap' he's dealing with.

GE cars do not have a resistor pack because they have High IMP. injectors. GTE cars do have the resistor packs cause they have low IMP. injectors... If you are using Low IMP. injectors, you need a resistor or you'll fry the injector drive transistors in the ECU. Nothing of what I said in that post that you quoted had anything to do with a GE setup. The only Refererance that I made about a GE was in the next post about the fuel pump resistor being the same between both a GE and a GTE setup.
Let me make one correction to what I said before, I forgot that the early GE cars (with yellow top injectors) did have a resistor pack but it was the same resistor pack as the GTE cars. Later GE's (with green top injectors) did not have the resistor pack.
So it the car is an early GE (thus having a resistor pack) its the same as a all year GTE's...

ok..just trying to help here.
i went 86.5 -Turbo. and i change the injector resistor pack to a turbo car, as well as the fuel pump relay/resistor pack, trying to help out the post. thats only what i read..and its good so far.

Yeah, in your case, you did have a injector resistor pack but there was no need to change it as it is the same part as what was on your car.... there is only one resistor pack that toyota used on all MKIII's that needed the resistor pack....
Regardless of the situation, if its not hooked up an his then that is his whole problem. If it is there and hooked up then he has another problem elsewhere....
Edit: I just went and looked at his profile and its showing his car to be a 92 which if it was a 92 GE like Im assuming, then he never had a resistor pack to begin with so if he didn't install one and plug it in, then there is his whole problem most likely....
yeah it's a ge shell with a gte engine and electronics, grey plugs... 91 targa harness and jdm ecu. I do not have the injector resistor. I will either find it or have to purchase one somewhere....
If you have already tryed to start your supra with out the injector resistor pack in place and have the low imp injestors in, your ecu also might be smoked. opps. hard way to learn.
