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

Check the power and ground. The brown wire for ground and pink for power
I bet you a chocolate covered doughnut that you left the ground wire to the back of the intake manifold off, because thats precisely what happened to me when I removed my cylinder head LMAO. Tens of hours checking EVERYTHING and reading the electrical schematics 50 million times. Then in a moment of clarity I remembered the ground strap and the sucker started right up.

At least your oil system is primed real well after all the cranking with no fire, just make sure to run it at 2000 rpm for about 20 minutes so your cylinder head wears in properly. And baby it for a couple hundred miles. I would also suggest double checking the valve shim clearance after you get it broken in.

Good luck dude and Im here if you need me




*EDIT*
Ok I just crawled under the car to verify(damn now im dirty), and on the 5SFE the ground strap actually comes out of the harness that is by the fuel injectors. It drops out of the harness between cylinder 2 and 3 injectors and I have it attached to the bolt that goes through the support bar( the one that goes from the block near the oil pan to the intake) on the intake. Hopefully that is your problem, the engine will come to life, angels will fly down from heaven and all will be good.
