no fire Options

1995 toyota celica st usdm

i just reinstalled my 7afe after ripping out the ecu wiring harness and motor
replaced the block with a jdm 7afe and used my head and intake manifold of my stock usdm
had the head reseated and reserved installed it all back in and now i have no spark?

i had some spark when i used the jdm ecu but with my stock ecu it didnt fire at all
the jdm ecu made the the ground wire on the passenger side burn up where the wire was showing so i replaced it
but now it didnt wanna fire at all. i know the jdm ecu was for coil packs but i thought i could try it anyways hopefully i didnt f something up

what do i need to do? replace ECU and Wiring harness and distributor all at once and try to start it up again?
i really dont wanna have to buy anything i dont need i did find a guy with a 94 celica st that said he would sell me his wiring harness and ecu for 150 buck


i need some help thanks

jdm engine install

my old ecu no spark after reinstall

Jdm ecu sparked at first but after i continued to try and start it it died

the engine after i put my old head back on with distributor

That check connector has all ground wires in it I believe. To my knowledge it is specifically for checking the grounds not the transmission.

Yes the pink should be in a different connector The fact that iit has power means that the ignition, relays and fuses are okay. And the grounds are the brown and white with black stripe. But its the brown wires that you want to check


edit***
I checked the wiring schematic and pink should be pin 2 on the 12 pin connector, at least it is on the 5SFE. Ground wires will be the pins along the outter edges of the 26 pin plug. In the schematic all the computer's grounds, white with black stripe and brown, all run together to the ground strap on the intake manifold.

If you are getting good ground here then I am going to say you have a bad ECU. If you are not getting ground through the Brown and W-B(white-blackstripe) wires then you are potentially 10 minutes away from fixing it and starting the engine. Stick one lead of the multimeter into the Brown or W-B wire at either the ECU plug or at the white check connector. Now hold the other lead of the multimeter to a good ground on the vehicle and check for continuity( the arrow running into a plus sign symbol). Make sure that you are using a good ground for the test, as every surface of the car is treated with a protective coating such as paint which does not conduct electricity and isnt a good ground. You might check for continuity between two bolts screwed into the floorboard under the dash(possibly good grounds) to verify that you have indeed found an acceptable ground (one of the two bolts) for the test. Let me know how the test goes I might make a video for this tomorrow if you want to wait till then
