yes i have changed the bulb with same result. what details am i missing that could help

 

Not to jack your thread but I'm having the exact same issue here.

D16y8(OBD2b) swap into 97 LX sedan using LX(OBD2a) harness. EVERYTHING is hooked up and working EXCEPT for the engine light. It does not come on at all.

-everything is plugged in
-starter works and cranks over
-checked the cluster with new bulbs and another cluster
-checked all the power/ground connection
-checked all the fuses
-I tried with two different ECU's:: the original ECU and P28 with conversion harness.
-I get no fuel:: because the engine light doesn't come on, the fuel pump doesn't prime.

It's almost as if I didn't plug in the ECU and/or pulled the ECU fuse out. I'm running out of ideas.

anybody else?

 

nice jack move apprecifate it

 

fixed the problem... This time, I sanded/cleaned all the surfaces for ground in the engine bay including the main harness ground.

I hope this helps.

 

did sanding the grounds work for you also?
