ok, so when i start my car up everythings fine, but after about 5-10 seconds the cel comes on all or a sudden and stays on. now i tried jumping the connector to read the code and when i do the cel just goes off and doesnt come back on or blink... it even came on and i shut the car off and jumped the connector and turned the car to the on position and the cel just went off and didnt blink or anything and never came back on... so as of right now it wont read the code and i dont know why.

the car runs fine and has no noticible problems that i can tell, it also drives perfectly fine.

 

Are you sure your reading it correctly? If you believe that there is no problem, reset the ECU. If there is indeed a problem the "CEL" should pop back up. If not then it should be gone.

 

i dont know how i would read it wrong when the light comes on and stays on once i start it, then when i try to read the code it just goes away and doesnt come back or blink or anything...

 

so i pulled the ecu fuse out today for about 5-10 minutes and put it back in and started the car, the cel didnt come on after about 5-10 seconds but instead came on about 5 minutes later, once it warmed up. but then every time after that it comes on after about 10 seconds again now when start the car...

 

are you jumping it right?
try jumping it while its running then while its off,
code reader?

 

i did try when its running, but as soon as i put the wire or paper clip into the connector the cel just goes off and doesnt come back on, blink or anything, then as soon as i pull the wire out of the connector the cel comes right back on...

 

are you running a stock motor? stock map sensor any thing that isnt stock? injectors? info on the motor setup would help greatly

 

no its a fully built b18b1, sleeved, bored, all internals in bottom end and head, p&p, gt42 turbo w/ fmic, all bolt ons, hondata s300 ecu, type r oil pump, 255lph fuel pump, type r transmission w/stage 4 racing clutch and 6 puck disc.... the only thing thats stock is the injectors (tune shop told me to keep them in until i bring it to get tuned) and the map sensor... the boost is only between 4-6lbs and the a/f gauge says im running a little rich, and my fuel pressure gauge says its at 40psi.

 

dude u have s300 .... did u try looking att error codes in smanager? hondata tells u what codes u r throwing

thats the awsome thing about s300 , no more primitive code reading

 

i would do that but i just dont have a lap top right now, mine took a ****
