Recently swapped a UK s14a SR20DET into a jdm kouki s14 silvia which had a SR20DE. I also used the engine harness from the UK car.

Currently the injectors won’t fire, although they’re getting power, just no ground signal from the ecu to make them fire, but it’s getting spark just fine. If I send a manually ground signal from either side of the harness they fire.

I’m not completely convinced it’s the ecu as it was all working completely fine when it was in the UK car. It’s also had NATS removed.

Has anyone done this swap before and overcome this issue?

Thanks
 
I’m having the same problem with my early I’m s14 and can’t seem to find out why. If you gets yours sorted post your fix up and hopefully will be of some help to others aswell
 
Mangaged to solve the issue for mine, ended up being the ECU.

After trying a different s14a ECU which DEFINIATLY had nats removed it fired straight up.
