I recently bought a 01 Integra, it wasent running before, and I thought i had fixed the problem, but having issues when starting in the morning when its cold. The starter will kick, but engine will not start, but after awhile trying to start, it will putter trying to stay on. Then after letting the car putter for some amount of time, It will magically correct itself from the putter, then run like a champ afterwards. I have no check engine lights. I NEED SOME SERIOUS HELP BEFORE I BLOW THE DAMN THING!

Things i replaced:
-The WHOLE Distributor
-Spark plugs, Spark plug wires
-Fuel Pump
-Main Relay

I unsure what else to check for, I dont think its a fuel issue. This only happens if the car is left sitting for the night, or long period of time.

 

Sounds like it could be a spark issue, what throws me off is that you say the car ends up running fine after it's done puttering...

 

how is you gas mileage?

 

End it up finding out it was the ecu. I don't think it's fried, since it starts up after awhile. Maybe just a loose solder or something, but I have a question for people who have 00-01 integras. If I replace the ecu, would I need the dealer to repogram, the immobilzer to work with the key?

 

hmmm are u sure its the ecu cuz u said it run just fine when its warm up. it could be your temp sensor. cuz when your temp sensor is bad your car would gave a fault reading of about 180 so it thing its in a close loop cycle. So when you car start in the morning its already think its warm so its gave it less fuel then it needed. so your car would run rough until it warm up. but once your car warm up it would run just fine. like u can turn it off and back on as long as it still warm it will run just fine

 

I dont think you have to get it program theres no chip in those keys, just swap it and try it, by the way how did you find out it was the ECU?
