Default code18?

Thanks for everybody'* help.

I replaced my starter and she runs like a top.

I did notice that I had a SES light and using a staple between the a & b terminal I got 1 long followed by 18 short. VIN L

I could not find anything for that combo.

Anybody run into this before?

Thanks

Click on "Quick Links" above, go down to "User Control Panel" and then click on "Edit your Signature" It'* pretty straight forward from there.

Thx Purp.

I have a 90 burb, and have pulled codes off that the same way. In fact, I've reprogrammed the ECU on that.

So, I guess I should have asked if leaving the ECU in this 1994 Bonnie 3800 overnight without power could trigger a code 18 or cable around the starter could get crushed, cut or pulled and cause a code 18.

Thanks again

Ok,

I rechecked the codes and with a little patience, code 43 popped up as well.

43 knock sensor
or electronic spark control circuit fault

Can anybody shed some light on what I need to do?

Thanks

All,

here'* a quick update. I disconnected the battery, and waited 30 seconds. fired her up. SES light gone.

Drove about 10 seconds and poped up again.

Now it'* only complaining about code 43.

WHere is the knock sesnsor on a 93 bonny Vin L?

Thanks

This thread might help you find them. There are two. One on each side of the motor. https://www.gmforum.com/t204257/

I was on the autozone site and there is a rough diagram but it showed the VIN L had one...

Thanks for the reply
