the fuel pump is running and wired correctly. i found some real wiring diagrams specifically for the 87 7mgte. so i need to check my wiring and see where i missed something. http://www.turboninjas.com/mk3supra/ feeling good about it now. thx for the encouragement. i will let you all know what i...

when i get it back together i will re check the timing. i have grounded the engine a couple of places but i am going to add a few more

yea, i have boost leak tested it 3 times with low psi compressed air. and i have smoke tested it as well then added some psi. i will try to post up another video soon. i need to put it back together to start it. i was able to pick up a analog boost gauge so i can see what it is doing better than...

thank you for the info. i swear i have almost read every page in the fsm and other factory bulletins but never got that. do you all think it sounds like a boost leak? i do but i cant find it? would this be the symptoms of a bad turbo? wastegate?

ok there smarty, no joke the fpr is sopose to have a vac line on there. I WAS ASKING what RPM the fuel up vsv activates to bump the fuel pressure up. so obviously you dont know.... this is not a straight supra, is is only the motor and it has been swapped into a 1980 truck. i have been...

yea stock fpr and it has the vac line going to the fuel up vsv

picts of the plugs. gapped at .028

just compression tested it. #1-145 2-145 3-145 4-145 5-145 6-135 also i dont have the factory boost sending unit hooked up. the wiring showed that it went to the gauge only. what rpm does the stock trim start to boost? when does the fuel up vsv open? it does not matter if the fpr has vac or not.

the j tube is still on the block not drilled out but i bypassed it and it is going straight to the fuel return pipe to the tank.

the walbro was the only one inline and nothing in the tank. so the walbro was up on the fender of the truck in the engine bay and i did not think it could lift the fuel it needed to fuel up when the rpms went up. so i fabbed up the intank one to act like a lift pump. it does not make a...

i need your help again. i fixed the tps wiring and the tps is working perfect (as you will see in the video it shows how much throttle is open in volts). itis a bone stock 1987 7mgte motor. there is a hesitation, stumble, hiccup at around 2500 rpm. it is running very rich and getting...

ended up being bad wiring from the tps to the ecu. ran new wires from the tps to the afm/eng temp sensor and ecu. fixed the problem

sounds good. what do you mean by "leads"?

yes i tested it correctly multiple times. it is a high flow pump and not loosing pressure or flow when it is acting up. the plugs are at .030. thinking it is the tps sure to the rising acceleration with the thrott barely cracked. i am not new to motors or fabrication. just the 7m

it wont drive normal. from idle to 1800 it runs perfect. sometimes it will rev right through. if i am over the bad spot like in one of the videos if the throttle is cracked it will act like it is floored. boot leak tested it with smoke and also with soap water on everything. no leaks. the...

so this started as a cel 52 i rewired it with new rg58 wire and it fixed the cel. the problem was this hesitation. as soon as the hiccup would happen the cel 52 would come on so i thought it was a knock sensor problem. now there is and are no cel codes showing or stored. but between 1800-2800...

i am going to start another thread since the code 52 is gone and it is a solid hesitation issue now. replaced the tps with a new one and adjusted perfect to spec. it acted the same as with the last used one i replaced the original one with. i will post a link to the new thread. SO IN SUMMARY -...

i wish i had any kind of access to one.

well i swapped the tps for another one i had from a 22re that was the same part #. it seemed to help some. but i could usually accelerate hard through the 2-3k spot. but still does it. i get correct reading on all of the test points now unlike the other original one. so that is good, but still...
