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

The ECU is grounded to the intake manifold. There is a ground wire coming off of the firewall that needs to bolt to the intake manifold. When you turn the ignition key to the ON position, the Check Engine Light will light up and remain on until the engine is started to show that the ECU is recieving power. If the check engine light does not come on with the other warning lights your ECU is not powering up.

Get out your multimeter and check for continuity between the SOLID BROWN wire going into the ECU and any grounded metal part of the body. If there is no continuity then you have left the ground wire off, a very common mistake. You can either check this brown ground wire at the plug going into the ECU or at the small clear/white connector that is capped off next to the ECU. This small connector is a diagnostic port. Make sure that when you remove any wires from the ecu to turn the car off and disconnect the battery. With the battery reconnected, the key 'ON' and the harness disconnected from the ECU check the SOLID PINK wire using your multimeter for 12volts against any ground on the vehicle. The pink wire is your power wire. Also check the EFI fuse and relay, these are the main source for the ECU's power
