Hey there, new guy here

Car is a 1992 Honda Accord LX, automatic, 227k on the clock.
Runs like a champ, doesn't burn oil or leak it.

Has a tough time starting in cold weather. If I let it sit overnight it takes about 5-6 times to start it. This includes turning it over, it starting for a second, then sputtering out. When it finally starts going it's pretty rough (below 700rpm) then goes up to high idle. A CEL comes on, and the D4 light blinks on the dash. It doesn't seem to miss any gears, and runs fine afterwards.

The code doesn't get stored so I can't check what it is. Any ideas?

 

Welcome to HAF.

So when you jump the service connector....what does the CEL, D4, ABS (if it has it) or SRS (again, if) lights do?

 

Nothing different. I'm assuming the jumper i'm jumping is right. Just a blue two wire plastic plug. When i took the kick-panel off, there was a larger black plug with a clear end over that.

 

Hello new member and Welcome

 

"Nothing different", not sure what that means.

 

with jumped does the same as without jumped. The CEL comes on for a few seconds then turns off, but doesn't come back on. If I start it and it doesn't have any issues starting, there is no check engine light. If I restart it after I've had an issue starting it, the code isn't stored in the engine.

if that makes any sense.

 

This is a hard one for me.....sounds like an ecu issue, lights blink but no code stored.

There is a tiny little ground on the T-Stat housing, lower hose connects to engine. Remove it and clean the contact points and re-install........see what you have from there.

Another thing to try, if this happens again.....don't shut the car off and jump the service connector an see if any codes are "present".

 

I will do that and get back to you.

 

I tried jumping the connector while the car was running, and no code flashes happened. As soon as i turned the car off the code was gone again, too.
