Kastigir Posted April 10, 2005 Share Posted April 10, 2005 Call an Acura dealer, they can tell you how to do it. There should be a light, try under the carpet in the passenger floorboard. If that's not it, post here and I will find out where the light is. Link to comment Share on other sites More sharing options...
scottywayne25 Posted April 10, 2005 Author Share Posted April 10, 2005 Yea..I ripped up the carpet.. all the way to the seat. i didnt find a light.. there wasnt an ecu or anything under the carpet.. the ecu is in the right kick panel and i was also told that there was a lil wiring harness that you can plug the prongs together with a paper clip or wire and it will show the codes thru the check engine light.. that was on a 92-95 civic tho.. they said the ecus should be very similar if not the same... they said the harness came outta the top of the ecu... didnt see it.i seen a harness but it had like 6 wires comin outta it.. not it.anyways thanks for helpin..i really appreciate it.. if you find out more just let me know Link to comment Share on other sites More sharing options...
Kastigir Posted April 10, 2005 Share Posted April 10, 2005 According to my friend who is a technician at Acura, there is a harness. You short out 2 wires and count the flashes of the Check Engine light. I'm not sure which 2 wires need to be shorted out. Monday I would call your local Acura dealer, they can help you more. Since my friend sees so many different Acuras, he can never really recall which is which. Link to comment Share on other sites More sharing options...
scottywayne25 Posted April 11, 2005 Author Share Posted April 11, 2005 Hey hey thanks for the help..i found out how to do it.. i noticed that there is a harness with 2 wires in it..a black one with a white stipe and a red one with a white stripe. I shorted out the wiring harness and my check engine light had a hard blink 4 times then 3 fast blinks. code=43 which means fuel supply system.. then i reset the ecu by pulling out the 2 fuses under the hood then i let it run for about 10 minutes to let the ecu figure out how my car runs again... then it led me to another problem... after a drive i figured i would check the ecu again.. and see if it threw another code... well this time the check engine light came on...and stayed on..didnt blink at all, didnt go off, or anything... I was just wondering what that meant if you might know...thanks for the help..its GREATLY appreciated Scott Link to comment Share on other sites More sharing options...
BigBirdSucks Posted April 11, 2005 Share Posted April 11, 2005 did you fix the fuel problem? Link to comment Share on other sites More sharing options...
Kastigir Posted April 11, 2005 Share Posted April 11, 2005 When the engine light comes on, it throws a trouble code. Pull the codes again and see what it says. If the old code was left over from a previous problem, it might be something different. Link to comment Share on other sites More sharing options...
scottywayne25 Posted April 11, 2005 Author Share Posted April 11, 2005 well its not left over from an old problem cuz ive reset the codes on the ecu about a month ago... it has a CAI on it and i can be driving down the road sometimes and itll throw a check engine light.. just happens everyonce in a while.. does that have anything to do with the fuel supply system code..ive also noticed that my car runs rich and on a 94 integra gsr ive heard that others usually get almost 300-375 miles outta a tank..well i get around 200 out of a tank.. if im lucky... I dunno whats wrong and does anyone know what the stock fuel pressure is supposed to be. just in case i check that..anyways..thanks for all the help.i relaly appreciate it Link to comment Share on other sites More sharing options...
