Hi, this is my first post here so sorry if this is the wrong place. I recently bought a 1989 Accord Lxi manual but I cant get it to run without starter fluid. I have 12 volts at all the injectors but when checking the control side the ecm wont pulse ground. The only way I can get the injectors to fire is to ground them from the ecm side.

My next step would be to check ecm grounds but I cant find a wiring diagram. Just looking for any suggestions or advice on what to do next 🎣

 

Are there any codes (check engine light on)? The ECU needs to see input from the crank angle sensor before it can fire the injectors.

always a good idea to double check your grounds.

 

Check the main relay under the dash, it often fails and can stop the ECU from firing the injectors. Also inspect ECU grounds near the thermostat and kick panel.
