when im driving my 88 si, the check engine light will come on and then die right after. I think its the main relay, cause sometimes it will not prime when i try to start it, but im not really sure. if it is main relay where exactly is it so i can replace it. any help would be greatly appreciated.

 

they are under the hood, and under the dash!

 

A CEL(check engine light) usually means the ecu is outputting an error code. Check your ecu led and count the blinks and that is the code. Look up the code in the manual or on here and find out what the problem is.

 

where can i find that on here

 

go to the ef forum and click new topic, after doing this type what code it is and a question mark!

 

Here is a few websites for the codes. Save them to your favorites.

Look here for replacing your Main Relay, which happens to be inside of the car and not in the engine compartment. That would be your main fuse.

Also, it's under the drivers side kick panel. Should say Mitsuba if it's the original.

 

thanks guys
