Hello, my name is Luis and I have a 1992 Honda Civic EG CX. Recently, I had an issue with a relay and replaced it, but I ran into some complications during the process. First of all, the dashboard wasn’t turning on, and the fuel pump wasn’t activating either, but I managed to fix that. Now the dashboard lights up, and the fuel pump does turn on, but there’s one problem… the check engine light doesn’t come on, and when I try to start the car, the starter motor cranks, but the engine doesn’t fire up. The fact that the check engine light isn’t turning on is what worries me the most.

I want to point out that my engine is a D15B8 with a B7 head, it’s multi-point fuel injection, and I’m using a P05 non-VTEC ECU. To make things worse, I can’t find internal diagrams for the P05 non-VTEC ECU. I don’t know what to do.. if anyone has any ideas, I’m all ears.
