ok i need help diagnosing a problem on my 2007 si coupe

when i turn my key to the accessory or on position all of my dash lights up and then off and back on and off repeatedly,this includes everything except rpm. sometimes my rpm will jump a little also maybe to say 1000 or 1200 and then it goes right back to 0 but not always.

there car is not turning over when i press the clutch in and continue to try to start is so it leads me to believe...

electrical ?

maybe ignition?

thanks for everyones help in advance.

 

Have you done any work on the car recently? Any other problems you have been having?

 

i have an intake leak about 1.5 or 2 inches before the Intake manifold and thats it. was gonna order takeda soon and bolt it on so i wouldn't hear it anymore lol.

thats the only thing really wrong .

:/

 

maybe your battery?

 

no tested and its fine. there was alot of corrosion on the positive though. cleaned it with coke and put some junk on it that suppossed to prevent corrosion.

 

the bad idle is from the leak not sure why the dash lights are like that

 

This is what I was going to suggest. I had the same thing happen to me. One day everything was fine, then the next morning I had a similar issue. I called my mechanic and he said change the battery. I did and everything was been fine. Seems when the factory battery goes, it goes all at once.

 

changed battery still happened. unplugged ecu at all 3 places and plugged it back up, running fine now.

go figure?

 

Must be running a Microsoft product :p Glad to hear its working again.

 

yea i was about to jerry rig it up get it running and trade it

 

bill gates your f*cking up!!
