hey guys, last time i went out to check my vehicle was not pulling codes.. what could be the problem here?

87 z28 carb'd 305.

anyone know where i can buy the complete harness to the ecm? and a new ecm.. i think mines faulty.

 

Make sure that the SES light works at key-on, engine-off. If not then no codes.

Don't know where to get a harness or new ECM. For a re-man ECM any decent auto store should be able to get one.

thanks for your reply will look into it, heading out now.

 

i think i need a new ecm also, any idea what they cost new?

 

i bought a new remanufactured ecm through my parts guy they list at $190. downfall is didn`t fix my problem (same as yours) and the are not returnable. but i now have the ecm ruled out, going to order a new prom next and try that

 

yeah mines still not pulling codes and i have no idea what it is, i have an orange wire hanging off my battery cable to the positive (orange end on the wire) idk.

 

ses is not working on key on.
