Ok, so i swapped in a y8 in my 89 hatch, wired everything up been taking my time, used my d16a6 harness etc...

Turn the key to on to check for fuel leaks etc, and I get no cel at all, so my fuel pump isnt even coming on, any idea's what it could be? Ecu was working before, and its not throwing a solid cel on the ecu or dash, just nothing.. I went over all the plugs and connectors and everything is secure and tight. I never really changed any wiring at all, just extended a few, but even so it should still at least prime the pump or give me a cel.

Any suggestions, I dont have a spare ecu ATM im gonna try and snag one later today.

 

Is A13-MIL MIL (check engine light) Blu/wht connected.

 

Didnt check, but like i said, everything was working 100% 2 days ago, and the ecu doesnt flick on, so its not getting power or its toast. I'll check that wire here in a minute

 

Check main relay also,

 

Yeah i was gonna, will that cause no cel to come on?
