my 92 accord shuts off
my 1992 accord shuts down after 5 minutes of running then i cant restart until the engine cools down. The ECM is throwing a no ignition output signal code.
i have confirmed by back probing at the ECM. Checked power and grounds at ECM all okay. Confirmed correct resistance through crank, cylinder, and TDC sensors. Tried replacing ECU but nothing changed. techs or knowledgeable peeps only please thank you!

Which circuit did you check by backprobing?
The "ignition output signal" is the circuit where the ECU tells the ignitor to fire the coil, so it can be open or short in the wiring from the ECU to the ignitor. Or (I guess) a bad ignitor.
