i have a 91 hb w/ a 93 b18 in it, and im throwing code 15. i know that it is the ignition output signal, but how do i fix it? thanks

 

ignitor - but the tests to determine if that is bad is to be performed by the dealer service dept - so says the haynes. do they use a scope to verify ???
the tests in the haynes involve the wires that come into the ignitor.
but in your case, the car does start, right ??

 

yea, it runs fine.

 

bump.....

 

yup it's the ignitor. i have one for sale if you need it
