Just like the title states.

I have a known bad ecu that runs in limp mode. My car will start with that, but run like crap because it's in limp mode.

When I substitute it for a known good ecu I do not get injectors firing.

I have 12v at the injectors. and fuel at the rail, so the ecu is not grounding them out.

What can cause this?

For future searchers, The CYP sensor inside of the distributor will cause the injector circuit to fail.

During limp mode the ECU ignores the CYP sensor.

That is why my limp mode ecu would run the car, but my good ecu would not

Honda only needs one sensor to run in limp home, and that is the TDC sensor, it will make shitty decisions based on that.
