Ignition Signal Loss
Hi guys!
So I have a 94 accord with a f22b2 engine. The problem I am having is that the car will lose ignition signal randomly. It seems to do it more when I first start the car and periodically for a short time after. Obviously the symptoms I am having are that it stalls and typically will not restart. Sometimes it will start back up but stalls again shortly after.
So I know it is losing ignition signal because when it stalled last I checked the ignition input to the distributor and there was no voltage on the pin. I am also fairly certain the switch. Is not the issue since I have tired jumping the pins in the switch connector and while sometimes it will start and run this way, often it is the same as trying to start with the key.
I am hoping one of you will know what could cause the ignition signal to disappear from the distributor.

15 is the signal FROM the ECU out to the distributor. The ECU thinks the circuit isn't sending the signal properly, so maybe look for continuity and/or shorts in the wiring from ECU to distributor.

There is an ohm check you can do at the distributor, then if that checks out do the same at the computer plug. There is a place on here to get the service manual, it has step by step for this check.

I had the same problem recently. It turned out to be the ECU. Had a couple blown capacitors. $25 and a visit to the junkyard later, I swapped the ECU and it start up and ran great.
